Guide
The species-level account. Cultivar pages build on this and say where they differ.
Ruellia californica is native to the arid northwest of Mexico, so it is adapted to strong sun and long dry spells. Give it the brightest spot you have, gritty fast-draining mix, and let the soil dry well between waterings. Water only when the top two inches of mix are fully dry, then water deeply.
