Guide

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

Peperomia argyreia is a small subshrub to epiphyte in the Piperaceae, with thick, water-holding leaves and stems that store moisture and rot easily if kept wet. Its epiphytic tendency means it wants fast-draining mix and airflow at the roots rather than constant moisture. Let the top inch or so of mix dry out before watering, and err toward letting it run dry rather than staying damp.

ToxicityAuthoritative · species

Non-toxic to cats & dogs
