A dense, conical-to-narrow-pyramidal evergreen tree native to eastern and central North America, prized as a screening and foundation conifer. Flat, fan-like sprays of scale-like, aromatic yellow-green foliage clothe the tree from the ground up, and red-brown bark exfoliates on mature trunks. Wild trees can reach 40-60 feet but cultivated plants typically stay near 20-30 feet; small urn-shaped cones and dense evergreen cover make it valuable food and shelter for birds.

A large, long-lived deciduous forest tree of temperate and montane Europe, prized for its dense domed crown, smooth grey "elephant-skin" bark, and glossy leaves that emerge silky-edged in spring and turn warm russet in fall. POWO (Kew) records it as native from France, Germany and Great Britain east to Ukraine and south to Italy, Sicily and the Balkans. It is one of the great cathedral-canopy hardwoods of Europe and an unrivalled clipped formal hedge — but it is a true forest tree, not a small-garden specimen, and the honest catch is the shade it casts: very dense, with shallow, greedy roots, so little will grow beneath an open-grown beech.

A native eastern + central North American multi-stemmed deciduous shrub with dentate (toothed) foliage, white spring flower clusters, blue-black drupes, and reliable fall color. Especially valued for wildlife — among the most-cited native shrubs for fall-migration bird forage.

Black elder (Sambucus nigra) is a fast, tough, wildlife-rich deciduous shrub native across Europe, north Africa and western Asia (POWO). It earns its place twice a year: broad flat creamy-white flower umbels scent the garden in early summer, then drooping clusters of small black berries ripen in late summer to feed birds in quantity. RHS gives the ornamental forms (e.g. "Black Lace") the Award of Garden Merit and rates the species fully hardy (H6). It is also one of the classic foraging shrubs — the flowers and the COOKED ripe berries are much-used for elderflower cordial and for elderberry syrup, wine and jam. The honest catch is real: the raw berries, and the leaves, bark, stems and roots, are toxic (cyanogenic glycosides) and cause nausea and vomiting, so berries must always be cooked and never eaten raw or unripe. Vigorous to the point of suckering and seeding about, elder is a wildlife and hedgerow plant first, an ornamental second.

A native eastern North American multi-stemmed deciduous shrub or small tree with white spring flower clusters, edible dark-blue drupes, and red-purple fall foliage. Among the most adaptable native viburnums; tolerates a wide range of soil + light conditions.

An upright, multi-stemmed, suckering deciduous shrub in the olive family, grown for its intensely fragrant mid-to-late-spring (May) bloom of lilac-purple flowers in large conical panicles. Native to southeastern Europe and cultivated in North America since the early 1600s, it matures to 12-16 feet tall with blue-green, pointed-ovate to heart-shaped leaves. It needs cold winters and cool summers — and offers few ornamental features after bloom, with leggy form, no fall color, and summer powdery mildew.
