Guide

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

A member of the prayer-plant family (Marantaceae) native to the humid forests of eastern and southern Brazil, this is a tropical understory plant that wants warmth, steady moisture, and protection from direct sun. Keep it in bright indirect light and water when the top inch of the mix is just dry, allowing it to approach dryness but not bone-dry. It is sensitive to dry air and low humidity, so steady ambient moisture suits it best.
