Guide

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

A woody shrub or small tree from Taiwan, this Hibiscus is a sun-loving plant that wants several hours of bright, direct light to stay vigorous and flower. Water when the top inch or two of mix has dried, then water deeply; it tolerates a brief approach to dryness better than sitting soggy. As a larger woody plant it draws steadily during active growth, so check the soil more often in warm, bright conditions.
