Habanero chillis (Capsicum chinense) — Annual or short-lived perennial grown as an annual outside USDA zones 10-11 (NC State Extension).
Timing is the decision that matters most in the USA: there are 7 separate regional planting out windows, ranging from early February in Deep South & Gulf Coast to mid May in Intermountain West.

Rows marked derived are interpolated between regions our sources do state, because no source we consulted gives a figure for that region specifically. They are deliberately wider to reflect that uncertainty.
Pacific Northwest - detail & sources
DERIVED from this region's own frost normal, not quoted for the region. Start seedlings indoors; do not transplant outside until nighttime temperatures reliably reach 55F, which is typically one to three weeks after the last frost date. Applied to a mean last frost of 8 March (NOAA NCEI 1991-2020 for the USA; Environment and Climate Change Canada normals for Canada), that gives 15 March to 29 March. Your own local frost date is what matters — a region spans a range, and this figure comes from one representative station within it.

-
Native to Bolivia, northern Brazil and Peru. USDA hardiness zones 10a-11b. Plant out only once nighttime temperatures reach at least 55F. 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 55F+ 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.

Very hot chilli peppers from the Amazon region, fruit 2-6cm long ripening from green to orange, red, white, brown, yellow or purple. Grow in loam or sand (acid/alkaline/neutral), moist but well-drained or well-drained, full sun, south/west-facing, sheltered. Hardiness H1C (5-10C 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.

Frequently Asked Questions
When should I plant habanero chillis out in the USA?
In Deep South & Gulf Coast, from early February. In Intermountain West, wait until mid May. Treat these as a guide rather than a fixed date — the governing rule is to plant out only once frost risk has passed and temperatures are reliably warm enough.
What soil pH do habanero chillis need?
A pH of about 5.5–8. That span reflects genuine variation between the authorities we cite rather than a single agreed figure — the References section lists each source's exact range.
What problems affect habanero chillis?
Our data links 2 diseases and 8 pests to this crop. See the sections above for each one and how to manage it.
Plan next season before the problems start
Almost everything on this page resolves to your own frost dates rather than the calendar — the last spring frost moves by roughly two months between zone 3 and zone 10. The USA Garden Planner works from your zone so the timing is already decided before the season starts.
