Noted for its exfoliating bark and showy fall color, award-winning Acer griseum (Paperbark Maple) is a small spreading deciduous tree that is highly desirable. The chestnut-brown bark of both its trunk and branches constantly peels into thin, tight curls, revealing brighter cinnamon-red wood beneath. Even the youngest stems contribute to this pleasing peeling bark effect. Equally attractive is the foliage of three-lobed leaves, typical of most Acers. Dark green above, but frosty blue-green underneath in spring and summer, the delicately textured leaves turn brilliant red and orange in the fall before shedding for the winter.

Densely branched with an upright, roundish habit, this slow-growing maple tree is an outstanding four-season tree.

Betula nigra 'Heritage' is a beautiful river birch prized for its incredible peeling bark. Salmon-cream to brownish at first, it exfoliates to reveal a creamy-white inner bark that can almost rival the European white birches.

The foliage of diamond-shaped, serrated bright green leaves deepens to dark green as the season progresses, before turning pale yellow in fall. It can be grown as either a single trunk or a multi-stemmed tree. Perfect for wet soils, 'Heritage' can tolerate locations with drier soils and is extremely resistant to bronze birch borer and leaf spot diseases.

Noted for its abundant flowering, the quality of its foliage, and its pleasant fall colors, Hamamelis x intermedia 'Pallida' (Witch Hazel) is one of the most popular hybrid Witch Hazels and one of the finest winter-flowering shrubs.

Native to China, Heptacodium miconioides (Seven Son Flower) is a unique plant with year-round interest. This large, fountain-shaped, multi-stemmed, deciduous shrub features clusters of fragrant, creamy-white flowers at the branch tips over a long bloom season from late summer to early fall. The blooms appear in whorls, with each whorl containing 7 small flowers (hence the common name of Seven-Son Flower). They are a great source of nectar for butterflies and hummingbirds in the fall and are followed by even showier crops of purplish-red fruits crowned by eye-catching rose calyces which last into late fall. The large, heart-shaped leaves are shiny green and deeply veined. Heptacodium miconioides remains attractive in winter when strips of pale bark peel away to reveal dark brown inner bark. No serious insect or disease problems
