   Native to Bolivia, northern Brazil and Peru. USDA hardiness zones 10a-11b. Plant out only once nighttime temperatures reach at least 55°F. Thrives in heat, tolerates drought (though prolonged drought reduces fruit quality). Full sun (6+ hrs). Soil pH acid (<6.0) to alkaline (>8.0), clay/loam/sand/high organic matter, rich moist well-drained. Spacing 12in-3ft. Height 1-2.5ft, width 1-2ft. Start seedlings indoors, transplant at 55°F+ nights. Common pests: aphids, whiteflies, cutworms, pepper maggots, Colorado potato beetles. Diseases: Verticillium wilt, mosaic virus (unspecified strain). Fruit is a non-pulpy berry with high capsaicin content, harvested summer and fall in gold, yellow, orange, purple, red or white.

Grow in loam or sand (acid/alkaline/neutral), moist but well-drained or well-drained, full sun, south/west-facing, sheltered. Hardiness H1C (5-10°C min) -- best grown indoors on a sunny windowsill or in a greenhouse, or outside only after frost risk passes. Height 0.5-1m, spread 0.1-0.5m. Time to maturity 1 year. Sow indoors late winter to early spring; pinch out growing tips at 20cm to encourage bushiness. Water regularly, feed with high-potassium liquid fertiliser once first fruit sets. Susceptible to glasshouse red spider mite, whitefly, aphids, slugs, snails, and grey mould. Irritant if eaten; causes skin/eye irritation -- wear protective equipment when handling. Family Solanaceae.
