Cockspur Hawthorn is a small, low-branched tree, also grown as a tall shrub. Flat clusters of white flowers with a somewhat unpleasant odor bloom in late spring, followed by bright red fruits in late summer. The fruits persist into winter, providing a food source for birds. The shiny green leaves turn bronze to red in the fall. This plant has 2-inch-long thorns, so avoid planting in areas with small children. Crus-galli in Latin means “leg of a cock,” referring to the resemblance of the formidable thorns to a cock
Sweet Fern is not a fern, but a multi-branched, mounded shrub with dark green, aromatic, fern-like leaves. Its inconspicuous, yellow-green catkins (elongated, drooping clusters of tiny flowers without petals) appear April-May, followed by small, burr-like nutlets. It is a host plant for butterfly and moth larvae (caterpillars), including Gray Hairstreak (Strymon melinus). This plant fixes its own nitrogen, and can tolerate sandy, nutrient-poor soil. It also tolerates wet conditions, as well as drought. Sweet Fern will form dense colonies once established. Use in naturalized areas, rain gardens, and on slopes for erosion control.
Maryland Goldenaster’s clusters of daisy-like, bright yellow flowers bloom August-October, adding color to the fall garden. This drought-tolerant plant grows well in dry, sandy soils. Use it in borders or wildflower gardens, along woodland edges, or as a groundcover in partly shady areas.
Common Hackberry is a medium to large, wildlife-friendly deciduous tree. It is monoecious (separate male and female flowers on the same plant); the tiny, greenish flowers bloom in April-May. The female flowers produce round, fleshy, dark purple, berry-like fruits valued by birds and wildlife as a food source. Berries can cause tree litter, so avoid planting this tree near walkways and sidewalks. It is a host plant for butterfly and moth larvae (caterpillars), including Wild Cherry Sphinx (Sphinx drupiferarum), Tawny Emperor (Asterocampa clyton), American Snout (Libytheana carinenta), Question Mark (Polygonia interrogationis), and Mourning Cloak (Nymphalis antiopa). Common Hackberry can tolerate a wide range of soil conditions and air pollution, making it suitable for urban areas. Use it as a lawn tree or street tree.
New Jersey Tea is a low-growing, wildlife-friendly deciduous shrub. Showy, fragrant, white flower clusters bloom May-July and are good fresh-cut. The flowers are a nectar source for hummingbirds, butterflies, and native bees. New Jersey Tea is a host plant for butterfly and moth larvae (caterpillars), including Spring Azure (Celastrina “ladon”), Mottled Duskywing (Erynnis martialis), and Summer Azure (Celastrina neglecta). Young, yellow twigs add color to the winter landscape. The common name originated when the dried leaves were used as a tea substitute during the Revolutionary War. Use New Jersey Tea in shrub borders, wildlife gardens, or as a groundcover on slopes.
Pignut Hickory is a large deciduous tree with yellowish-green leaves turning golden-yellow in the fall. It is monoecious (separate male and female flowers grow on the same tree); the non-showy flowers bloom April-May. The female flowers are followed by nuts, but not until the tree is about 25 years old. The nuts are inside husks, which split open in the fall when ripe; the nuts are a food source for wildlife. Early settlers called this tree Pignut Hickory when they found their hogs would eat the nuts, which are too bitter for human consumption. This tree is a host for butterfly and moth larvae (caterpillars), including Luna Moth (Actias luna), Funerary Dagger (Acronicta funeralis), and Giant Regal (Citheronia regalis). It tolerates both dry and moist soils. Give this large tree plenty of room to grow! Use Pignut Hickory as a tall shade tree in large yards and in parks.
European Hornbeam is a medium-sized deciduous tree with a lovely, oval shape. Its smooth, gray bark has vertical grooves, giving the appearance of rippling muscles along the trunk. It is monoecious (separate male and female flowers grow on the same tree). The small, greenish female and yellowish male flowers appear in March before the leaves emerge, followed by drooping clusters of small nutlets in the summer. The leaves turn yellow in the fall. Use European Hornbeam as a shade or street tree. It can also be used as a hedge or screen planting; it responds well to heavy pruning, which is best done from fall to mid-winter.
