Guide

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

Iresine diffusa is a soft-stemmed subshrub from a wide range of warm American habitats, from tropical forest margins to subtropical scrub, so it favors warmth and steady but not soggy conditions. Give it bright indirect light to keep its foliage full, and water when the top inch of mix has dried, letting the surface approach dryness between drinks rather than staying wet. It dislikes cold and sustained saturation at the roots.
