A giant herbaceous perennial from Southeast Asia and the principal wild ancestor of most cultivated dessert bananas. What looks like a trunk is a 'pseudostem' — tightly rolled leaf sheaths — topped by a fountain of huge, paddle-shaped leaves that can run 6-10 feet long, giving an instant tropical effect. In frost-free climates (USDA zones 10a-11b) an established clump produces a drooping flower spike and a hanging bunch of edible fruit, then that pseudostem dies and is replaced by a sucker from the base. It is frost-tender: everywhere colder it is grown as a bold container or greenhouse foliage plant that is overwintered indoors and rarely, if ever, fruits.

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.

A tropical evergreen tree from the lowland rainforests of western and central Africa, grown almost everywhere else as a dramatic indoor specimen for its huge, glossy, fiddle- (or violin-) shaped leaves with bold sunken veins. In its native habitat it becomes a 40-foot tree, but as a houseplant or patio container plant it is typically kept to a single upright 6-15 foot trunk topped with a sculptural rosette of leaves. Winter-hardy only in the frost-free subtropics (USDA zones 10-12); everywhere colder it is a houseplant. It is famously fussy: it wants bright, steady light, even moisture, warmth, and — above all — to be left in one spot, dropping leaves in protest at cold drafts, moves, or erratic watering.

A broadleaf-evergreen citrus tree reaching 15-30 feet tall and wide, with glossy foliage, sharp thorns on its twigs, and highly fragrant white four-petaled flowers. The large fruit (over 3 inches across) ripens pale yellow, often patched with pink, over juicy flesh that ranges from near-white to deep red by cultivar. A subtropical tree hardy only to USDA zone 9a, it is grown outdoors across the citrus belt and as an overwintered container plant farther north.

A bold tropical fig from South and Southeast Asia grown almost everywhere as a houseplant for its large, glossy, leathery, deep-green (or cream- and burgundy-variegated) paddle leaves. Honesty first: in its frost-free native habitat and outdoors in USDA zones 9-12 this is a massive strangler-type fig that can reach 50-100 feet with a spreading, aerial-rooting crown — but in the homes, offices, and patio containers where almost everyone grows it, it is kept a fraction of that size by pot confinement and pruning. It is easygoing in bright indirect light and forgiving of average indoor conditions; the one real catch is its milky latex sap, a mild skin, eye, and digestive irritant that also bothers latex-sensitive people. The same latex was historically tapped to make natural rubber, which is where the name comes from.

A tender tropical evergreen shrub grown for its enormous, flamboyant flowers — broad funnels of red, pink, orange, yellow, or white, single or double, each with a long protruding column of fused stamens. Native to tropical Asia (a cultigen of such ancient cultivation that no certain wild origin survives), Hibiscus rosa-sinensis blooms continuously in warmth above glossy, dark green, evergreen leaves. Each flower typically lasts only a day, but a healthy plant opens fresh blooms in steady succession from spring through fall — and year-round in frost-free climates. It is the classic hibiscus of warm-climate landscapes and patio containers: heat- and humidity-loving, frost-tender, and hardy in the ground only in USDA zones 9a-11b.
