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.

The leading acid citrus — a small broadleaf-evergreen tree to 10-20 feet, usually armed with sharp thorns on the twigs, bearing fragrant white flowers (purplish beneath) that ripen into the familiar oval, nipple-tipped yellow fruit dotted with aromatic oil glands. A tender subtropical: hardy outdoors only in USDA zones 9-11, but a classic large-container plant that can summer outside and overwinter indoors in colder climates. Native to Asia, not North America.

A small subtropical evergreen tree grown for its sweet, fragrant fruit and glossy aromatic leaves. Originally domesticated in subtropical Asia from a cross between a mandarin and a pomelo, it carries clusters of up to six fragrant creamy-white flowers in early spring that ripen into round-to-oval orange fruit 2-5 inches across. Hardy outdoors only in the warmest US zones (9-11) but readily grown as a container plant brought indoors for winter in colder climates.

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 warm-season annual vegetable in the nightshade family, grown for fresh summer fruit. Tomatoes need full sun, consistent moisture, slightly acidic soil, and night temperatures above 50°F. Larger fruits like beefsteaks can struggle in extended hot southern summers because flowers drop without setting fruit.
