Douglas fir
Pseudotsuga menziesii
A very large Pacific Northwest conifer — 40-80 feet in cultivation but topping 300 feet in the wild — and one of the most important timber trees in North America. Unique forked, trident-shaped cone bracts that protrude between the scales distinguish it from every other conifer. Flat, spirally-arranged dark green needles are fragrant when bruised and leave raised circular scars on the twigs.

Populus deltoides
Eastern cottonwood
One of the largest and fastest-growing native hardwoods of eastern and central North America — a streambank and bottomland tree reaching 50-80 feet (occasionally far more) with a broad, open-rounded crown. Its glossy triangular (deltoid) leaves with coarse marginal teeth and flattened petioles flutter and clatter in the wind, and female trees release the cottony seed fluff that gives the tree its name. Fast, tough, and tolerant of drought and urban conditions, but messy and weak-wooded — Missouri Botanical Garden calls it generally inappropriate for ornamental or urban use, better suited to rural lowspots and stream corridors.

Celtis occidentalis
Common hackberry
A tough, widely adaptable native shade tree of central and northeastern North America, growing 40-60 feet tall and wide with a rounded, spreading crown. Mature gray bark develops the warty corky ridges that make it instantly recognizable, and the round purple drupes are edible and feed dozens of bird species. One of the most pollution- and stress-tolerant street and shade trees available — it shrugs off wind, urban conditions, and wet, dry, or poor soils alike.

Juniperus virginiana
Eastern red cedar
A tough, aromatic native conifer of eastern North America — actually a juniper, not a true cedar — with scale-like evergreen foliage and a broadly conical to columnar form. Missouri Botanical Garden calls it the most drought-resistant conifer native to the eastern U.S., thriving on limestone glades, fence rows, and abandoned fields. It is dioecious: female trees carry the powdery blue, berry-like cones that gave the cedar waxwing its name and feed many birds and small mammals through winter.

Prunus serotina
Black cherry
The largest native cherry of eastern North America — a medium-to-large deciduous shade tree that hangs elongated racemes of small white flowers in spring, then ripens drooping strings of pea-sized fruit from red to near-black in late summer. The fragrant white bloom feeds bees while the fruit is eaten by 33 species of birds and many mammals; it is also a workhorse larval host, supporting the Eastern Tiger Swallowtail and a string of giant silk and sphinx moths. Every part except the ripe fruit is cyanide-bearing and toxic.

Ostrya virginiana
American hophornbeam
A small-to-medium understory tree of dry, rocky eastern-North-American woods, named for its drooping clusters of papery, sac-like seed pods that resemble the fruit of hops. The birch-like, sharply-serrated leaves turn an undistinguished yellow in fall, and reddish-brown male catkins persist on the bare branches through winter. Also called ironwood for its extremely hard, dense wood; tough, low-maintenance, and drought-tolerant once established.
Prunus americana
American plum
A small native deciduous tree (or thicket-forming, suckering shrub) of eastern and central North America, grown for clouds of fragrant white 5-petaled flowers that open in March before the leaves and for the edible red plums that follow in early summer. It forms a broad, spreading crown with attractive dark reddish-brown twigs that sometimes carry thorny lateral branchlets. A documented larval host for swallowtails and other butterflies, with flowers of special value to native, bumble, and honey bees.

Juglans nigra
Black walnut
A large deciduous timber and nut tree of eastern North America, growing 75-100 feet tall with an oval to rounded crown and dark, deeply furrowed diamond-patterned bark. Pinnately compound leaves carry 13-23 strongly aromatic leaflets, and yellowish-green flowers in May-June ripen into hard-shelled edible nuts inside green husks. Its roots and tissues release juglone, a compound that suppresses azaleas, rhododendrons, blueberries, peonies, and tomato-family crops planted nearby.
Quercus macrocarpa
Bur oak
One of the most majestic native North American oaks — a slow-growing, long-lived member of the white oak group that the Missouri Botanical Garden lists at 60-80 feet (occasionally to 150) with an equally broad, rounded crown. Named for its large acorns whose cups are fringed with a mossy, bur-like scale near the rim. Notably drought- and clay-tolerant, it ranges from southeastern Canada through the central United States, and may take up to 35 years to bear its first acorn crop.
Celtis occidentalis
Common hackberry
A tough, widely adaptable native shade tree of central and northeastern North America, growing 40-60 feet tall and wide with a rounded, spreading crown.
