Guide

The species-level account. Cultivar pages build on this and say where they differ.

Crossandra infundibuliformis is an evergreen subshrub from warm regions of South Asia and tropical Africa, where it grows in dappled understory light. It prefers bright indirect light and evenly moist but never waterlogged soil; let the top inch of mix dry before watering again, then water thoroughly. It tolerates average household humidity but appreciates a touch more warmth and moisture in the air.
