Guide

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

A small Brazilian Peperomia that grows as a subshrub or epiphyte, with thick, water-storing leaves that let it tolerate drying between waterings. Give it bright indirect light and a fast-draining mix, and water only when the top inch of mix is dry, since its fleshy stems and roots rot if kept wet. Average household humidity suits it.
