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.

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 to 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.

Jelly palm, also sold as pindo palm, is the cold-hardy feather palm of southern Brazil (Rio Grande do Sul) and Uruguay, and one of the hardiest feather-leaved palms in cultivation. For decades it was treated as Butia capitata, and nurseries and several references still sell and describe this palm as Butia capitata, although Kew's WCVP accepts Butia odorata and the true B. capitata is a more tropical, less hardy palm that is rare in gardens. It is a slow-growing, single-stemmed palm of 15 to 20 feet with a stout trunk knobbed by persistent leaf bases and a crown of long, arching, strongly recurved blue-green to gray-green leaves whose stalks are edged with sharp teeth. Large sprays of small, fruity-scented cream to yellowish flowers are followed by clusters of edible yellow to orange fruit about 1 inch across, sweet and fibrous around a hard stone and traditionally made into jelly or wine. UF/IFAS rates it hardy to about 10°F, and notes that it survives in south Florida but grows much better in cooler, less humid climates. It is not documented as invasive, though Wikipedia records occasional naturalized populations in the southeastern United States.

Achiote, also sold as annatto or lipstick tree, is a fast-growing evergreen shrub or small tree native from Mexico through Central America to Colombia, Venezuela, the Guianas, Ecuador, Peru, Bolivia, Brazil, Paraguay, and northern Argentina, and planted across the tropics for its seeds. Clusters of pink or white flowers about 2 inches across, like single wild roses, open at the branch tips and are followed by clusters of red to red-brown capsules covered in soft bristles, which split open to show seeds coated in a waxy red-orange layer. That coating is annatto: the coloring and mild seasoning behind achiote paste and sazón, the yellow-orange of many cheeses, butters, and margarines, and the red body paint and lipstick that gave the plant its English name. In a garden it usually stays 6 to 12 feet tall and wide as a specimen or informal hedge, though as a tree it can reach 20 to 30 feet. It is frost-tender and needs a frost-free climate: it is hardy outdoors in USDA zones 10a-12b and grown elsewhere in a large container or conservatory that comes indoors before frost. Outside its native range it has naturalized on many Pacific islands, sparingly so in Hawaii, and in the Galapagos, where the Charles Darwin Foundation rates it potentially invasive.

Camellia sinensis is the evergreen shrub whose leaves, buds, and stems yield every style of tea - white, green, oolong, and black - and it is native to the monsoon-forest borderlands of SW China, Myanmar, northeast India, and mainland Southeast Asia. In gardens outside zones 7–9 it is too frost-tender to grow unprotected outdoors, and the honest catch is its unyielding demand for reliably moist, acid soil (pH 4.5–6.5): on anything alkaline or prone to summer drought it yellows, stalls, and refuses to thrive no matter how warm the climate.

A broadleaf-evergreen citrus tree reaching 15 to 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.
