Guide

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

The triangle palm is a Madagascan tree from seasonally dry, open habitat, so it wants strong light and gritty, free-draining mix that never stays soggy. Let the top two inches of mix dry fully before watering, then water deeply; it tolerates drought far better than wet feet. Indoors, give it the brightest spot you have and good airflow.
