Eggplant

A bold, upright warm-season annual from the Andes, grown in gardens for its long, rope-like tassels of tiny blood-red flowers that hang straight down from the stem tips and leaf axils from July until frost. The same species is kiwicha, an Andean grain and leaf crop cultivated for thousands of years, including by the Incas, and it is also called Inca wheat. Garden plants usually reach 3 to 5 feet, with drooping tassels typically to 12 inches long and occasionally to 24 inches; selections with yellow-green tassels exist, and grain types carry heads in white, red or black. The tiny seeds are eaten cooked, popped or ground into flour, and the leaves are eaten like spinach, but grow it without chemical fertilizers if you plan to eat it, because the leaves concentrate nitrates on nitrogen-rich soil. It is frost-tender and grown for a single warm season in every zone.

A terrestrial bromeliad grown for its sweet, golden, edible fruit - the abacaxi of warm Brazil. POWO records it as South American in origin, its precise wild range obscured by ancient domestication, and Flora e Funga do Brasil documents Ananas in Brazil. The plant forms a low rosette of stiff, sword-shaped leaves, many forms armed with sharply toothed margins, from the centre of which a single stout stem rises bearing a dense cone of small purple flowers. Those flowers fuse together into the familiar multiple fruit (a syncarp), topped by a leafy crown that can itself be rooted to grow another plant. HONESTY: this is a frost-tender tropical, hardy in the ground only in roughly USDA zones 10a-11b, and it is slow - a plant takes well over a year from planting to a ripe fruit. Commercial clones are largely self-incompatible and, kept isolated from other clones, set the seedless fruit prized in the kitchen.

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 fast cool-season annual of the mustard family grown for its peppery, mustard-like salad greens - irregular, pinnately-lobed basal leaves in a low rosette, each with 4 to 10 small lateral lobes and a large terminal lobe (Missouri Botanical Garden). First cultivated by the ancient Greeks and Romans and still widely grown across Europe, it is best grown in the cooler spring and fall months rather than summer heat; leaves are harvested young and tender before they turn strong and bitter. Pale-yellow four-petalled flowers with dark brown or purple veins appear in corymbs if plants are left to bloom.

A cool-weather leafy cabbage relative grown for its broad, leathery, blue-green leaves that grow in a loose upright rosette on a thick stem - never forming a head ("acephala" is Greek for headless). A biennial almost always grown as an annual, it sweetens after a fall frost and, in mild-winter regions, keeps producing leaves through winter until it bolts in spring. One of the most cold-tolerant vegetables in the cabbage family.
