Roselle
Hibiscus sabdariffa
An upright, frost-tender warm-season annual mallow domesticated in West Africa and now grown throughout the tropics for its edible calyces (GBIF). It carries red stems, lobed leaves, and pale-yellow hibiscus flowers, but the prize is the fleshy, deep-red CALYCES that swell around the seed pod after each flower fades — the source of the famous ruby "hibiscus" / roselle / bissap tea, syrups, and jam. The young leaves are also eaten as a sour potherb. It needs a long hot season and full sun to flower and set its calyces, and because it is short-day it flowers only as the nights lengthen in autumn, so in cool-summer climates it may run out of season before the harvest matures.

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.

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).

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.

Laurus nobilis
Bay laurel
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 10-30 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.

Punica granatum
Pomegranate
A multi-stemmed deciduous shrub or small tree cultivated for millennia for its orange-sized, leathery-skinned edible fruit packed with juicy seed arils. Glossy oblong leaves back showy orange-red summer flowers that ripen into the crowned, persistent-calyx fruit. Drought-tolerant and at its best in long, hot, dry summers with cool winters; grown for hedges, specimens, and Mediterranean-style gardens where winter-hardy.
Citrus x aurantiifolia
Key lime
A vigorous, shade-intolerant small evergreen tree (or large shrub) native to tropical southeastern Asia, grown for very juicy, aromatic green-to-yellow fruit with a thinner rind than Persian lime. Glossy, leathery, distinctively aromatic leaves frame showy five-petaled white flowers — purple-tinged when new — that can appear across all four seasons in warm climates. Strictly tender: NC State lists it for USDA zones 9a-11b, and it does not tolerate standing water, flooding, or shade.
