What Is an Ixora?
Ixora is a large genus of flowering plants native to the Asian tropics. At least 400 species have been identified in this genus, with a handful being popular for cultivation. These plants grow in USDA zones 10 and 11, preferring tropical to subtropical climate conditions. People outside the growing range can cultivate Ixora in the greenhouse, if they are able to create tropical conditions. Nurseries and garden stores in tropical areas usually carry at least one cultivar of Ixora, and they can also order specialty plants by request.
