Botanical Name: Cornus alternifolia KOR-nus all-ter-nih-FOE-lee-ah Common Name: Pagoda dogwood, Green osier Genus: Cornus
This plant owes its name to its distinctive layered branches, which resemble the tiered, spreading roofline of an elaborate pagoda. Pagoda dogwoods are especially striking when accented by masses of small, fragrant creamy white flowers in early summer. Small, round fruits ripen to a deep blue-purple in late summer.
Noteworthy characteristics: Native to North America, from Newfoundland to Minnesota, southward to the extreme southern Appalachians, and westward to Missouri. Performs best near its native range. Tolerates more cold, wind, and alkaline soil than flowering dogwood.
Care: Grow in moist soil in partial shade.
Propagation: Root from softwood and hardwood cuttings. Also grown from seed.
Problems: Dogwood blight, powdery mildew, canker, bacterial leaf spot, and mushroom root rot. Common: twig borers, weevils, sawfly, scale insects, aphids, leafhoppers, root knot nematodes, and thrips.

This large, fast-growing tree has droopy leaves that stay sunny yellow from spring until frost, spiny shoots, and fragrant white flowers in late spring and early summer on pendent racemes. The flowers are followed by smooth brown seed pods that are also interesting. 'Frisia' is one of the cultivars that is grown more for foliage than for its flowers and it does not flower as freely as the species.

Lemon-lime foliage, fuzzy stems, and intense fall color make this sumac cultivar a standout. It grows into an upright, rounded form about 6 feet tall and as wide. New growth emerges chartreuse. Fall brings leaves of yellow, scarlet, and orange. Flowers are yellowish green and followed, on female plants, by hairy, dark red fruit. This plant spreads by suckers and can be invasive. The species is native to North America.

'Schubert' choke cherry has a pyramidal form and vivid foliage that makes it a great focal point. Abundant, dark red-purple fruit follow the ephemeral, light pink flowers. The fruit is attractive to birds, so 'Schubert' choke cherry should not be planted near patios or walks due to the calling cards well-fed birds leave behind. Ask if the tree you buy is grafted onto nonsuckering rootstock; otherwise, suckers could pose problems down the road.
