Oregano is a warm-temperate herbaceous crop that grows best in the 17–28°C range with 700–1300 mm of rain, cropping over a 180–300-day season.


Oregano is the leaves of a low plant, gathered above the ground.
Climatic suitability only — scored for every 0.5° of the planet from this crop's temperature and rainfall tolerances (FAO EcoCrop) on AgroClim 1991–2025 normals (AgERA5 temperature, CHIRPS/ERA5 rainfall). It shows where the rain-fed climate permits the crop, not where it is grown today; irrigation lets many crops thrive in drier country than the map suggests (California, Egypt, the Indus and Nile).
Deep bar = optimal range; pale bar = absolute tolerance. Beyond the pale bar the crop fails. Latitude tolerance ±—° · soil pH 4.5–8.7.
An annual cycle of roughly 180–300 days from sowing to harvest, so it is timed to fall within the frost-free, adequately-wet part of the year for the location.
