A rounded, multi-stemmed deciduous shrub native across eastern and central North America, grown for its edible nuts and its season-opening catkins. Showy 2-3 inch yellowish-brown male catkins dangle from bare branches in early spring before the ovate, double-toothed leaves emerge; small egg-shaped edible nuts ripen inside leafy husks by mid- to late summer. Easygoing in average soil and tolerant of clay and black walnut, it suckers into thickets that screen and shelter wildlife.

Care tips

•

The single most important tip is honest: do NOT plant Japanese honeysuckle where it can escape into wild or unmanaged land - across much of the eastern and central US it is an invasive noxious weed.

•

Plant the native coral honeysuckle (Lonicera sempervirens) instead for a fragrant climbing honeysuckle with strong hummingbird value and no invasive risk.

•

If this vine is already on a property, control it aggressively - cut and remove stems before berries ripen, never compost or dump prunings (stems root where they touch soil), and follow up on resprouts and bird-sown seedlings.

Lifecycle

Planting

Tolerates full sun to part shade and average, medium-moisture, well-drained soil - and frankly almost any soil, which is part of the problem. It is undemanding to start, but the only responsible advice is not to introduce it to new ground: where it can reach unmanaged land it will escape. Choose the native coral honeysuckle (Lonicera sempervirens) instead.

Transplanting

It transplants and re-roots with discouraging ease; stems root readily where they touch moist soil, so even moved fragments can re-establish. This same trait is exactly why it spreads so aggressively and why discarded prunings must never be left lying on the ground.

Early growth

Growth is rapid once roots take, with little need for supplemental water after establishment. The early vigor that looks attractive in year one is the same vigor that lets it overtop and smother neighbors within a few seasons.

Maturity

A mature plant is a long-lived, large semi-evergreen vine that twines into the canopy of shrubs and small trees and forms dense ground-covering mats in the open. At maturity it produces fragrant flowers and black berries that birds spread, seeding new infestations well beyond where it was planted.

Propagation

Spreads with notorious ease by seed (bird-dispersed berries), by stems that root at the nodes, and by underground runners. This reproductive vigor is the engine of its invasiveness - which is precisely why it should not be propagated or planted in regions where it escapes.

Brugmansia suaveolens

Angel's trumpet

Angel's trumpet (Brugmansia suaveolens) is a large, soft-wooded shrub or small tree hung with enormous pendulous trumpet flowers - up to 12 inches long, white aging to soft blush, and intensely fragrant in the evening and at night. Native to the Atlantic Forest of south-eastern Brazil (POWO, Kew; Flora e Funga do Brasil), it is now classified Extinct in the Wild by the IUCN and survives only in cultivation, which makes a familiar garden plant quietly remarkable. It grows fast and thirsty in warmth (USDA zones 9b-11b) and is frost-tender, so in cold-winter areas it is grown in a large container and overwintered under cover. The load-bearing warning is its toxicity: EVERY PART IS HIGHLY TOXIC, loaded with tropane alkaloids (scopolamine, atropine, hyoscyamine), and poisonings can be severe or fatal - never plant it where children or pets could reach it.

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.

The Mediterranean evergreen whose leathery, glossy dark-green leaves are the bay leaf of the kitchen. Missouri Botanical Garden PlantFinder describes it as a pyramidal, aromatic evergreen tree or large shrub that can reach 60 feet but is usually seen at 10 to 30 feet and is often pruned to 8 feet or less for garden use. Trees are dioecious: small yellowish-green spring flowers on female plants, if pollinated, give way to single-seeded purple-black berries. Winter hardy only to USDA Zone 8, so it is grown as a clipped container houseplant farther north.

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.
