Guide

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

Anthurium clarinervium is an understory aroid from the limestone forests of southeastern Mexico, where it grows in dappled shade with constant warmth and humid air. Give it bright indirect light, a chunky free-draining mix, and let the top inch or two of mix dry before watering again, since its thick roots rot if left sitting wet. It is accustomed to high humidity and steady moisture rather than soggy soil.
