Guide

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

Gardenia jasminoides is an evergreen shrub from the warm, humid subtropical forests of East and Southeast Asia, where it grows in dappled light and consistently moist, well-drained, acidic soil. Give it bright indirect light and water when the top inch of mix is just beginning to dry, never letting it sit soggy or fully dry out. It is sensitive to dry air and cold drafts, so steady warmth and high humidity suit its nature best.
