Guide

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

A perennial of the Brazilian tropical understory, this Marantaceae wants warmth, steady moisture, and shelter from direct sun, which scorches its patterned foliage. Keep it in bright indirect light and water when the top inch of mix begins to dry, never letting it sit fully wet or bone dry. It comes from a humid forest floor and resents dry household air.

ToxicityAuthoritative · species
