Hardiness library

Is my plant cold hardy? Zone & min temp for 10153 species.

Pick a plant for its USDA zone, RHS rating, the lowest temperature it can actually survive, and a straight indoor-only-or-outdoor verdict. A tender monstera that dies below 10 °C reads nothing like a hardy lavender that shrugs off a hard frost — because the answer comes from each plant's real data, not a template.
