Yucca filamentosa is a species of flowering plant in the family Asparagaceae native to the southeastern United States as far west as Louisiana, and along the East Coast from central Florida to southeast Virginia. They have become naturalized north along the East Coast to coastal Rhode Island and into parts of the lower Midwest. They are normally hardy in USDA hardiness zones of 4b to 9. Most commonly found in sandy soils, especially in beach scrub and dunes, but also in fields, barrens, and rocky slopes, though it grows well also in silt or clay soils. Its common names include Adam's needle, common yucca, Spanish bayonet, bear-grass, needle-palm, silk-grass, and spoon-leaf yucca.

Usually trunkless, it is a multisuckering evergreen shrub with heads of 75 cm (30 in) long, filamentous, blue-green, strappy leaves. It is fully hardy, though in cultivation it benefits from a sheltered position away from winter winds. Y. filamentosa is readily distinguished from other yucca species by white, thready filaments along the leaf margins. Flower stems up to 3 m (10 ft) tall bear masses of pendulous cream flowers in early summer.

Y. filamentosa is widely cultivated in mild temperate and subtropical climates as a broadleaved evergreen plant. It needs full sun and a well-drained soil, preferring an acid or slightly alkaline pH range of 5.5 to 7.5. It develops a large, fleshy, white taproot with deep large lateral roots. Once planted and established, it is difficult to remove it as the deep roots keep sending up new shoots for many years.

 ‘Valley Forge’, a Dutch elm disease tolerant elm.
Over the past 50 years, millions of stately elms shading the streets of the American landscape
have been lost to Dutch elm disease (DED). Selected after 20 years of research, ‘Valley Forge’
has high levels of disease tolerance, although it is not immune to DED. This cultivar possesses
the classic American elm shape and the tolerance to air pollution and poor soil conditions of the
species. ‘Valley Forge’ is extremely vigorous and requires significant pruning and management
effort, which may make it unsuitable for street tree planting. However, as a source of exceptional
DED tolerance genes for elm breeding and research, ‘Valley Forge’ presents an exciting
opportunity to revive a classic street tree.

Grow in average, medium moisture, well-drained soils in full sun. Tolerant of light shade. Prefers rich, moist loams. Adapts to both wet and dry sites. Generally tolerant of urban conditions. Development of varieties that are resistant to Dutch elm disease is ongoing.

Noteworthy Characteristics

American elm is a medium to large deciduous tree, typically growing to 60-80’ (less frequently to 130’) tall with a vase-shaped, broad-rounded crown. It is native to eastern and central North America. In Missouri, it typically occurs in low moist ground and along streams throughout the state (Steyermark). Although once widely planted as a street and lawn tree, American elm populations have been so decimated by Dutch elm disease that this tree is no longer considered to be a viable selection for landscape uses. Insignificant small green flowers appear in spring before the foliage emerges. Flowers give way to single-seeded wafer-like samaras (each tiny seed is surrounded by a flattened oval-rounded papery wing). Seeds mature in April-May as the leaves reach full size. Rough-textured, ovate-elliptic, dark green leaves (to 6” long) have toothed margins and asymetrical bases. Leaves typically turn an undistinguished yellow in fall.

Problems

Dutch elm disease, a fatal fungal disease spread by airborne bark beetles, attacks the water-conducting tissue of the tree, resulting in wilting, defoliation and death. Phloem necrosis is a disease caused by a phytoplasma that attacks the food-conducting tissue of the tree, usually resulting in a loosening of the bark, wilting, defoliation and death. Wetwood is a bacterial disease that results in wilting and dieback. Various wilts, rots, cankers and leaf spots may also occur. Insect visitors include borers, leaf miner, beetles, mealy bugs, caterpillars and scale.

Garden Uses

May be used as a lawn, shade or street tree. Not currently recommended for most landscape plantings due to Dutch elm disease. Disease resistant varieties such as Ulmus americana ‘Valley Forge’ are promising but not totally immune.

The Bur oak, is a specie of oak in the white oak section Quercus sect. Quercus, native to North America in the eastern and midwestern United States and south-central Canada. This plant is also called Mossycup oak and Mossycup white oak.

It is a large deciduous tree growing up to 30 m (100 ft), rarely 40 m (130 ft), in height, and is one of the most massive oaks with a trunk diameter up to 3 m (10 ft); reports of taller trees occur, but have not been verified. It is a medium grower oak, with a growth rate of 35 cm (1 ft) per year when young. A 20-year-old tree will be about 6 m (20 ft) tall. It commonly lives to be 200 to 300 years old, and may live up to 400 years. The bark is a medium gray and somewhat rugged.

The acorns are very large (probably the largest or the oak group), 2–5 cm (0.8–2 in) long and 2–4 cm (0.8-1.5 in) broad, having a large cup that wraps much of the way around the nut, with large overlapping scales and often a fringe at the edge of the cup. Bur oak is sometimes confused with Overcup oak and White oak, both of which it occasionally hybridizes with. Bur oak is cultivated by plant nurseries for use in gardens, parks, and as a street tree. Bur oak makes an outstanding ornamental tree. Among the white oaks, it is one of the most tolerant of urban conditions, and is one of the fastest-growing of the group. It has been planted in many climates.

Butternut is a deciduous tree growing to 20 meters (66 ft) tall, rarely 40 meters (130 ft). Butternut is a moderate-growing specie, and rarely lives longer than 75 years. It has a 40–80 cm stem diameter, with light gray bark. The leaves are pinnate, 40–70 cm long, with 11–17 leaflets, each leaflet 5–10 cm long and 3–5 cm broad. The whole leaf is downy-pubescent, and a somewhat brighter, yellower green than many other tree leaves.The native butternut, also known as white walnut, is the hardiest member of the walnut family. It is found throughout Southern Quebec and Ontario. Even though it has similar timber qualities to the black walnut, it is prized also as a carving wood.

When the green husk is removed, it reveals an oval dark brown shell with deep longitudinal ridges. The kernel is often caught in the shell cavities making the meat difficult to remove. Grafted cultivars have been selected for cracking quality. The butternut is very susceptible to the fungus disease Sirococcus claviginenti-juglandacearum, that causes cankers and open oozing wounds in the trunk, eventually killing the tree. It is estimated that over 90% of the trees in North America are infected. It is believed that the disease was introduced from offshore. The tree has been placed on the endangered list. It is believed that some trees are resistant to this disease. It may be possible to save this species through breeding.

The butternut leafs out and blooms at about the same time as heartnut, Persian walnut and Manchurian walnut. As a result it crosses readily with them. Along with hybrid vigor, low fertility and disease resistance, the crosses often exhibit the hardiness of the butternut and unfortunately the thick shell and poor cracking quality of the parents. Very few good hybrids have been identified. Only heartnut so far has made a noteworthy cross. They are termed buartnuts, the "bu" from butternut and the "artnut" from heartnut. Mitchell, from Scotland, Ontario is the best buartnut found to date. It is a productive tree having a nut shaped like a heartnut with the rough shell and hardiness of the butternut. This area in breeding has largely been neglected. It should be possible to extend the range of the heartnut through breeding with the butternut and existing buartnuts like the Mitchell.

Our Butternut seedlings come from 2 big trees (almost 3 feet in diameter) with no trace of Canker. We think that the parents tree may carry a very good resistance of the canker. We decided to produce our Butternut from those 2 parents. We have thousands of them available.

Common buttonbush is a multi-stemmed shrub which grows 6-12 ft. or occasionally taller. Leaves in pairs or in threes, petiolate; blade up to 8 inches long, ovate to narrower, sometimes 1/3 or less as wide as long, with a pointed tip and rounded to tapered base, smooth margins and glossy upper surface, lower surface duller. Glossy, dark-green leaves lack significant fall color. Flowers small, borne in distinctive, dense, spherical clusters (heads) with a fringe of pistils protruded beyond the white corollas. Long-lasting, unusual blossoms are white or pale-pink, one-inch globes. Subsequent rounded masses of nutlets persist through the winter. Trunks are often twisted. Spreading, much-branched shrub or sometimes small tree with many branches (often crooked and leaning), irregular crown, balls of white flowers resembling pincushions, and buttonlike balls of fruit.

Buttonbush is a handsome ornamental suited to wet soils and is also a honey plant. Ducks and other water birds and shorebirds consume the seeds.

Larix laricina, commonly known as the tamarack, eastern larch, black larch, red larch or American larch, is a species of larch native to Canada, from eastern Yukon and Inuvik, Northwest Territories east to Newfoundland, and also south into the northeastern United States from Minnesota to Cranesville Swamp, Maryland; there is also an isolated population in central Alaska. The word tamarack is the Algonquian name for the species and means "wood used for snowshoes." Larix laricina is a small to medium-size boreal coniferous and deciduous tree reaching 10–20 metres (33–66 ft) tall, with a trunk up to 60 centimetres (24 in) diameter. Tamaracks and Larches (Larix species) are deciduous conifers. The bark is tight and flaky, pink, but under flaking bark it can appear reddish. The leaves are needle-like, 2–3 cm (0.8–1.2 in) short, light blue-green, turning bright yellow before they fall in the autumn, leaving the pale pinkish-brown shoots bare until the next spring. The needles are produced spirally on long shoots and in dense clusters on long woody spur shoots. The cones are the smallest of any larch, only 1–2.3 cm (0.4–0.9 in) long, with 12-25 seed scales; they are bright red, turning brown and opening to release the seeds when mature, 4 to 6 months after pollination. Tamarack larch foliage and cones in August. The lighter brown cones are from the current season; the darker brown cones are mature cones from previous seasons.

It is very cold tolerant, able to survive temperatures down to at least −65 °C (−85 °F), and commonly occurs at the arctic tree line at the edge of the tundra. Trees in these severe climatic conditions are smaller than farther south, often only 5 m (16 ft) tall. Tamarack can tolerate a wide range of soil conditions but grows most commonly in swamps in wet to moist organic soils such as sphagnum peat and woody peat. The tree is found on mineral soils that range from heavy clay to coarse sand; thus texture does not seem to be limiting. Tamarack is commonly an early invader. Tamarack is generally the first forest tree to invade filled-lake bogs. In the lake states, tamarack may appear first in the sedge mat, sphagnum moss, or not until the bog shrub stage. Farther north, it is the pioneer tree in the bog shrub stage. Tamarack is fairly well adapted to reproduce successfully on burns, so it is one of the common pioneers on sites in the boreal forest immediately after a fire.

Acer campestre, common name field maple, is a maple native to most of Europe. It is a deciduous tree reaching 15–25 metres (49–82 ft) tall, with a trunk up to 1 metre (3 ft 3 in) in diameter, with finely fissured, often somewhat corky bark. The shoots are brown, with dark brown winter buds. The field maple is widely grown as an ornamental tree in parks and large gardens. The wood is white, hard and strong, and used for furniture, flooring, wood turning and musical instruments, though the small size of the tree and its relatively slow growth make it an unimportant wood. It is locally naturalised in parts of the United States but not in Canada yet. Suitable for zone 4b.

Laburnum, sometimes called golden chain, is a genus of two species of small trees in the subfamily Faboideae of the pea family Fabaceae. The species are Laburnum anagyroides—common laburnum and Laburnum alpinum. They are native to the mountains of southern Europe from France to the Balkans.

The Laburnum trees are deciduous. The leaves are trifoliate, somewhat like a clover; the leaflets are typically 2–3 cm (1–1 in) long in L. anagyroides and 4–5 cm (1.5–2 in) long in L. alpinum.

They have yellow pea-flowers in pendulous leafless racemes 10–40 cm (4–15.5 in) long in spring, which makes them very popular garden trees. In L. anagyroides, the racemes are 10–20 cm (4–8 in) long, with densely packed flowers; in L. alpinum the racemes are 20–30 cm (8–12 in) long, but with the flowers sparsely along the raceme The fruit develops as a pod and is extremely poisonous, it can be used medicinally.

The yellow flowers are responsible for the old poetic name 'golden chain tree' (also spelled golden chaintree or goldenchain tree). All parts of the plant are poisonous, although mortality is very rare. Symptoms of laburnum poisoning may include intense sleepiness, vomiting, convulsive movements, coma, slight frothing at the mouth and unequally dilated pupils. In some cases, diarrhea is very severe, and at times the convulsions are markedly tetanic. The main toxin in the plant is cytisine, a nicotinic receptor agonist.

Laburnum has historically been used for cabinetmaking and inlay, as well as for musical instruments. In addition to such wind instruments as recorders and flutes, it was a popular wood for Great Highland Bagpipes before taste turned to imported dense tropical hardwoods such as Brya ebenus (cocus wood), ebony, and Dalbergia melanoxylon (African monkeywood).The heart-wood of a laburnum may be used as a substitute for ebony or rosewood. It is very hard and a dark chocolate brown, with a butter-yellow sapwood.

Laburnum species and hybrids are cultivated as ornamental trees for gardens and parks. They are also trained as espaliers on pergolas, for ceilings of pendant flowers in season. Hardy to zone 5a

A first rate accent tree adorned with frothy upright panicles of creamy white flowers in early summer; interesting steel-gray bark and a dense, upright habit, an ideal choice for small home landscapes; needs full sun and well-drained soil.

Ivory Silk Japanese Tree Lilac features showy plumes of fragrant creamy white flowers rising above the foliage from late spring to early summer. It has dark green foliage throughout the season. The pointy leaves do not develop any appreciable fall colour. The fruit is not ornamentally significant. The smooth dark red bark adds an interesting dimension to the landscape.

Ivory Silk Japanese Tree Lilac is a dense multi-stemmed deciduous tree with an upright spreading habit of growth. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition.

This is a relatively low maintenance tree, and should only be pruned after flowering to avoid removing any of the current season's flowers. It is a good choice for attracting butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Ivory Silk Japanese Tree Lilac will grow to be about 25 feet tall at maturity, with a spread of 20 feet. It has a low canopy with a typical clearance of 5 feet from the ground, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for 40 years or more.

This tree should only be grown in full sunlight. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America but from the mountains in northern Japan.

Catalpa speciosa, commonly known as the northern catalpa, is a specie of Catalpa native to the midwestern United States. Suitable for ornamental plantation in zone 4b. It is a medium-sized, deciduous tree growing to 15–30 meters tall and 12 meters wide. It has a trunk up to 1 m diameter where there is an optimal climate zone, with brown to gray bark maturing into hard plates or ridges. The leaves are deciduous, opposite (or whorled), large, heart shaped, 20–30 cm long and 15–20 cm broad, pointed at the tip and softly hairy beneath. The flowers are 3–6 cm across, trumpet shaped, white with yellow stripes and purple spots inside; they grow in panicles of 10-30.

The catalpa tree is the last tree to grow leaves in the spring. The leaves generally do not color in autumn before falling, instead, they either fall abruptly after the first hard freeze, or turn a slightly yellow-brown before dropping off. The winter twigs of northern catalpa are like those of few other trees, having sunken leaf scars that resemble suction cups. Their whorled arrangement (three scars per node) around the twigs is another diagnostic.

The fruit is a long, thin legume-like pod, 20–40 cm long and 10–12 mm diameter; it often stays attached to the tree during winter (and can be mistaken for brown icicles). The pod contains numerous flat, light brown seeds with two papery wings. It is closely related to southern catalpa, and can be distinguished by the flowering panicles, which bear a smaller number of larger flowers, and the slightly broader seed pods. The wood is soft, like white pine, and light, weighing only 26 pounds per cubic foot when dry. It also does not rot easily.

Acer platanoides (Norway maple) is a specie of maple native to eastern and central Europe and western Asia, from France east to Russia, north to southern Scandinavia and southeast to northern Iran. It is a member of the sandalwood family.

Acer platanoides is a deciduous tree, growing to 20–30 m (66–98 ft) tall with a trunk up to 1.5 m (4 ft 11 in) in diameter, and a broad, rounded crown. The bark is grey-brown and shallowly grooved; unlike many other maples, mature trees do not tend to develop a shaggy bark. The shoots are green at first, soon becoming pale brown; the winter buds are shiny red-brown. Under ideal conditions in its native range, Norway Maple may live up to 250 years, but often has a much shorter life expectancy in North America, sometimes only 60 years. Especially when used on streets, it can have insufficient space for its root network and is prone to the roots wrapping around themselves, girdling and killing the tree. Norway Maples often cause significant damage and cleanup costs for municipalities and homeowners when branches break off in storms as it is fast-growing and does not have strong wood. Norway Maple has been widely placed into cultivation in other areas, including western Europe northwest of its native range. Partial sun when young well drain sol needed.

Laburnum alpinum is similar to Laburnum anagyroides, it grows to 5 metres (16 ft) by 6 metres (20 ft), at a fast rate. It is hardy to zone 5a or 5b. It is in flower from late May to June, and the seeds ripen from September to October. The panicles of vanilla scented, pea-like flowers are hermaphrodite (having both male and female organs) and are pollinated by insects. The fruit is a pod or legume, the seeds green at first but becoming shiny black.

The leaves are cholagogue and purgative. All parts of this plant are highly poisonous[5] and should not be eaten or used internally. It is native to Central and Southern Europe and has naturalized in Scotland. L. alpinium and L. anagyroides Medic. both are common as a garden escape in Northern Ireland. Laburnum alpinum is cultivated as an ornamental tree. Plants can be successfully transplanted even when quite large.

The plant prefers well-drained, light (sandy), medium (loamy) soil but tolerates heavy clay and nutritionally poor soils. Preferring acid, neutral and basic (alkaline) soils, it can grow in semi-shade (light woodland) or full sun. It can withstand strong winds but not maritime exposure and tolerates atmospheric pollution. The plant is notably susceptible to honey fungus.

Laburnum has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby.

Seedlings from large nuts

The black walnut is one of the most successful edible nut trees in southern canada. It is well adapted to our winter cold, and unlike Persian walnuts, avoids late spring frosts by delaying leafing in the spring. As a result it is suited to most of Southern Quebec and Ontario. A strain of black walnut has even adapted itself to the rigors of the dry fertile prairies (zone 3) of Manitoba. More limiting than climate is the soil type and drainage conditions. Black walnut succeeds well beyond its native range, wherever pH readings are between 6 and 7. Eroded limestone soils ranging from sand to clay are ideal. Deep well-drained soils are important to proper development and growth. The black walnut is a large deciduous tree reaching heights of 30–40 m (98–131 ft). Under forest competition, it develops a tall, clear trunk; the open-grown form has a short trunk and broad crown.

Even though the black walnut is well established in Ontario and we see more plantation in southern Quebec, the crop of delicious nuts it produces has not been utilized except by a few persistent foragers. The early pioneers highly valued the rich-tasting nuts and put away many sacks of them each year. Each farmstead had its orchard of fruit and nut trees to provide it with its source of winter food. Most of them all disappeared when easier cracking Persian walnuts became common in the grocery stores. With modern tree shakers, harvesters, nut hullers, crackers and sorting machines being available, it is possible to profit from the nut crop again. The industry is alive and well in Stockton, Missouri where millions of pounds of black walnuts are processed each year. The total kernel crop is marketed domestically. Almost none is left over for export.

Suitable for zone 4a.

Acer saccharinum, commonly known as silver maple, creek maple, silverleaf maple,soft maple, water maple,swamp maple, or white maple is a species of maple native to eastern and central North America in the eastern United States and Canada. It is one of the most common trees in the United States. The silver maple tree is a relatively fast-growing deciduous tree, commonly reaching a height of 15–25 m (49–82 ft), exceptionally 35 m (115 ft). Its spread will generally be 11–15 m (36–49 ft) wide. A 10-year-old sapling will stand about 8 m (26 ft) tall. It is often found along waterways and in wetlands, leading to the colloquial name "water maple". It is a highly adaptable tree, although it has higher sunlight requirements than other maple trees.

The leaves are simple and palmately veined, 8–16 cm long and 6–12 cm broad, with deep angular notches between the five lobes. The 5–12 cm long, slender stalks of the leaves mean that even a light breeze can produce a striking effect as the downy silver undersides of the leaves are exposed. The autumn color is less pronounced than in many maples, generally ending up a pale yellow, although some specimens can produce a more brilliant yellow and even orange and red colorations. The tree has a tendency to color and drop its leaves slightly earlier in fall.

The flowers are in dense clusters, produced before the leaves in early spring,[4] with the seeds maturing in early summer. The fruit are samaras, each containing a single seed, and winged, in pairs, small (5–10 mm diameter), the wing about 3–5 cm long. The fruit are the largest of any native maple. Although the wings provide for some transport by air, the fruit are heavy and are also transported by water. Silver Maple and its close cousin Red Maple are the only Acer species which produce their fruit crop in spring instead of fall. The seeds of both trees have no epigeal dormancy and will germinate immediately. On mature trunks, the bark is gray and shaggy. On branches and young trunks, the bark is smooth and silvery gray. Typical yellow autumn leaf color. Atypical reddish autumn color; this sort of coloration is sporadic and uncommon

Wildlife uses the silver maple in various ways. In many parts of the eastern Canada., the large rounded buds are one of the primary food sources for squirrels during the spring, after many acorns and nuts have sprouted and the squirrels' food is scarce. The seeds are also a food source for squirrels, chipmunks and birds. The bark can be eaten by beaver and deer. The trunks tend to produce cavities, which can shelter squirrels, raccoons, opossums, owls and woodpeckers.

Today the wood can be used as pulp for making paper. Lumber from the tree is used in furniture, cabinets, flooring, musical instruments, crates and tool handles, because it is light and easily worked. Because of the silver maple's fast growth, it is being researched as a potential source of biofuels. Silver maple produces a sweet sap, but it is generally not used by commercial sugarmakers because its sugar content is lower than in other maple species.

The silver maple is often planted as an ornamental tree because of its rapid growth and ease of propagation and transplanting. It is highly tolerant of urban situations, and is frequently planted next to streets. However, its quick growth produces brittle wood, and is commonly damaged in storms. The silver maple's root system is shallow and fibrous, and easily invades septic fields and old drain pipes; it can also crack sidewalks and foundations. It is a vigorous resprouter, and if not pruned, will often grow with multiple trunks. Although it naturally is found near water, it can grow on drier ground if planted there. In ideal natural conditions, A. saccharinum may live up 130 years, but in urban environments often 80 or less.

Following WW II, silver maples were commonly used as a landscaping and street tree in suburban housing developments and cities due to their rapid growth, especially as a replacement for the blighted American Elm. However, they fell out of favor for this purpose because of brittle wood, unattractive form when not pruned or trained, and tendency to produce large numbers of volunteer seedlings, and nowadays it is much less popular for this purpose to the point where some towns and cities banned its use as a street tree.

It is also commonly cultivated outside its native range, showing tolerance of a wide range of climates, growing successfully as far north as central Norway and south to Orlando, Florida. It can thrive in a Mediterranean climate, as at Jerusalem and Los Angeles, if summer water is provided. It is also grown in temperate parts of the Southern Hemisphere: Argentina, Uruguay, Venezuela, the southern states of Brazil (as well as in a few low-temperature locations within the states of São Paulo and Minas Gerais).

The silver maple is closely related to the red maple (Acer rubrum), and can hybridise with it. The hybrid variation is known as the Freeman maple (Acer x freemanii). The Freeman maple is a popular ornamental tree in parks and large gardens, combining the fast growth of silver maple with the less brittle wood, less invasive roots, and the beautiful bright red fall foliage of the red maple.

The swamp white oak, is a medium-sized tree of America's north central and northeastern mixed forests. It has a very large range, and can survive in a variety of habitats including wet soil. It is not found where flooding is permanent, although it is usually found in broad stream valleys, low-lying fields, and the margins of lakes, ponds, or sloughs. It grows rapidly and can reach 300 to 350 years. It is not a large tree, typically growing to 20-25m.

It is one of the more important white oaks for lumber production. In recent years, the swamp white oak has become a popular landscaping tree, partly due to its relative ease of transplanting.

Best grown in moist, well-drained soils in full sun. Tolerates some light shade. Best performance is in cold winter climates with cool summers. Site in areas with good air circulation to help rid the dense foliage of moisture. Somewhat intolerant of urban stresses such as air pollutants and salt spray. Plants will struggle in the high heat and humidity south of USDA Zone 6.

Noteworthy Characteristics

Picea glauca, commonly called white spruce, is an extremely hardy evergreen conifer that is native to upland areas and lake/stream margins stretching from Alaska across the boreal forest of Canada to Newfoundland, dipping south to Montana, Minnesota, Wisconsin, Michigan and New York. This tree typically grows 60-80' tall (less frequently to 140' tall) with a cone-shaped crown. It diminishes in size to low, shrubby forms near tree line in northern Canada. Blue-green needles (to 3/4") on small woody pegs have sharp tips. Needles are pungently aromatic when crushed. Needles have a glaucous (white waxy coating) bloom, hence the specific epithet and common name. Branchlets do not droop. Cylindrical pale brown cones (to 2.5" long) have flexible scales.

Genus name is reportedly derived from the Latin word pix meaning pitch in reference to the sticky resin typically found in spruce bark.

Specific epithet both are in reference to the fact that mature needles of this tree become glaucous (acquire a waxy white bloom) with age.

Problems

No serious insect or disease problems. Susceptible to needle and stem rust, canker, trunk and root rot. Yellow-headed spruce sawfly, spruce budworm and eastern spruce beetle are problems in some areas. Spider mites are common.

Easily grown in average, medium moisture, well-drained soil in full sun to part shade. Tolerates close to full shade, but usually at the expense of diminished fall color quality. This is an adaptable shrub that tolerates a wide range of soils except for wet, poorly-drained ones. Plants appreciate consistent moisture, particularly when grown in full sun locations.

Noteworthy Characteristics

Euonymus alatus, commonly called winged euonymus, burning bush, winged burning bush or winged spindle tree, is a dense, mounded, spreading, flat-topped, multi-stemmed shrub that is particularly noted for its fiery red fall foliage color. It is native to forests, woodlands and scrub areas in eastern Russia, Japan, China and Korea. It was introduced into the U.S. around 1860 as an ornamental, and over time has become an extremely popular shrub for homes, commercial properties and along highways. This shrub will mature over time to 15-20' tall, but is often pruned shorter. Elliptic to obovate, crenulate to serrulate, green leaves (to 3” long) turn bright red in fall. Fall color can be spectacular. Small, yellowish-green flowers appear in May but are not showy. Small fruits (1/3” red capsules) ripen in fall. Fruit capsules split open when ripe to reveal the tiny seeds (each encased in a fleshy orange-red aril). Seeds are attractive to certain birds who eat and distribute them. Greenish-brown stems have distinctive corky ridges ("wings" as used in the common name). Corky-winged stems are more noticeable in winter after leaf drop. Winged euonymus has escaped plantings and naturalized in at least 21 eastern and mid-western states. In some areas, it is now considered to be a threat to native plants because of its ability to establish itself in woodlands, forests, fields, roadsides and disturbed areas where, if conditions are favorable, it will out-compete native plants to form dense thickets.

'Compactus' is a popular burning bush cultivar. It is a deciduous shrub which is not all that "compact" since it typically grows in a mound to 10' tall with a slightly larger spread, though it can easily be kept shorter by pruning. The corky ridges are absent or very reduced in size on the stems of 'Compactus'. For a truly compact burning bush, see Euonymus alatus 'Rudy Haag' which typically grows from 3-5' tall.

Problems

No serious insect or disease problems. Twig blight may occur, particularly in wet soil conditions. Watch for spider mites.

Catalpa ovata, the yellow catalpa or Chinese catalpa, is a pod-bearing tree native to China. Compared to C. speciosa, it is much smaller, typically reaching heights between 6 to 10 m (20 and 30 feet). The inflorescences form 4–10-inch-long (10–25 cm) bunches of creamy white flowers with distinctly yellow tinging; individual flowers are about 1 inch wide. They bloom in July and August.[5] The leaves are very similar in shape to those of Paulownia tomentosa, having three lobes (two are abruptly truncated on either edge, with a third, central, slightly acute, pointed lobe forming the leaf apex), and are darkly green. Fruits are very narrow, foot-long pods. Hardy to zone 4a
