Chocolate vine
Akebia quinata
Chocolate vine is a vigorous, twining woody climber native to China, Japan, and Korea, producing clusters of spice-scented purple-maroon flowers in spring and large sausage-shaped fruits in autumn. It adapts readily to most well-drained soils in sun or part-shade and covers structures fast, making it a striking focal-point plant for walls, fences, and pergolas. The honest catch is its invasive potential: it smothers native shrubs and trees by blocking sunlight and is listed as invasive across much of the US East Coast and the Pacific Northwest, so it must not be planted where it can escape into natural areas, and annual hard pruning is essential to keep it under control.

Amelanchier canadensis
Canadian serviceberry
A small native tree with white spring flowers, edible summer berries, and copper to red fall color.
Sambucus canadensis
American elderberry
A fast, suckering native shrub of streambanks and moist thickets across eastern North America, grown for huge flat-topped cymes of tiny lemon-scented white flowers in early summer and the clusters of dark elderberry drupes that follow. Spreads by root suckers into naturalized colonies 5-12 feet tall and wide; the flowers feed butterflies and the showy fruit feeds birds. The raw berries are not eaten fresh — they are cooked into jelly, pie, and wine.
Diospyros virginiana
American persimmon
A tough, medium-sized native tree of the eastern and midwestern United States, grown as much for its showy edible orange fruit as for its distinctive thick, dark gray bark broken into rectangular blocks. Small urn-shaped white-to-greenish-yellow flowers open in May and June, and the sweet fruit ripens after frost. Largely dioecious — a female tree needs a male pollinizer nearby to set fruit — and notably drought- and walnut-tolerant once established.
Cornus mas
Cornelian cherry
A tough, adaptable deciduous large shrub or small tree, Cornelian cherry (Cornus mas) opens clusters of bright yellow flowers on bare stems in late winter — among the earliest woody nectar of the year — then ripens glossy red, olive-shaped edible fruit and finishes with good autumn colour. Native to central and southern Europe and western Asia (POWO), it carries the RHS Award of Garden Merit and is rated fully hardy (H6).
Corylus maxima
Filbert
Filbert (Corylus maxima) is a large deciduous shrub native to southeastern Europe and southwestern Asia, from the Balkans through to Ordu in Turkey, where it has been cultivated for its larger-than-hazelnut edible fruits for millennia. In the garden it doubles as bold structural foliage — especially the wine-purple cultivar 'Purpurea' — making it as much an ornamental as a productive shrub. The honest catch is its sheer bulk and suckering ambition: left unmanaged it rapidly forms an impenetrable multi-stemmed thicket 6–10 m tall, requires another Corylus nearby for worthwhile nut crops, and squirrels reliably harvest the nuts before the gardener does.
Diospyros lotus
Date plum
Date plum (Diospyros lotus) is a deciduous tree native from northeastern and south-central Turkey east through Iran, the Himalayas, and Central Asia to China and Korea, with a history of cultivation reaching back to antiquity — possibly the "lotus" of Homer's Odyssey. In gardens it offers glossy foliage, small greenish-cream flowers in summer, and ornamental fruit ripening to yellow then blue-black. The honest catch is twofold: the tree is dioecious, so a male is needed near a female for a proper seeded crop (a lone female sets only sparse, often seedless fruit), and the fruit is intensely astringent until fully ripe or frost-softened, so it is messy and unpalatable if picked early.
