Guide

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

Begonia obliqua is a member of the Begoniaceae, a family of tropical and subtropical understory plants that favor warmth, even moisture, and protection from direct sun. Give it a bright spot out of direct rays and let the top inch of mix dry before watering again; its fibrous roots resent sitting wet and are prone to rot. Most homes provide adequate humidity, though it will appreciate steady airflow and warmth above cold drafts.
