Anthurium clarinervium is a Mexican lithophytic aroid known for its thick, velvety, heart‑shaped leaves with bright white veins. The short version: it’s a slow-growing, humidity-loving rock-dweller that needs bright indirect light and a chunky mix.
Light
-
Bright indirect light (10,000–18,000 lux).
-
Direct sun bleaches the veins and burns the leaf; low light fades the pattern.
Soil
-
Needs a chunky aroid mix: orchid bark, perlite, coco coir, peat.
-
Avoid dense potting soil — roots require oxygen like a lithophyte.
Water
-
Water when the top 2–3 cm dries.
-
Never let it sit in water; rhizome rot happens fast.
