About African Mask Plant (Alocasia)
The African mask plant (Alocasia × amazonica 'Polly') is a hybrid whose parent species come from tropical Asia, grown for its dark, glossy, arrow-shaped leaves ribbed with bold pale veins. It stays upright at around half a metre on tall stalks, so a 4-litre pot suits it on a bright spot indoors. The looks are the draw, but it is the fussiest plant in this group and is better matched to a grower with some experience.
Keep the soil lightly moist but never soggy, and give it warmth and high humidity. Bright indirect light without harsh direct sun keeps the leaves dark and firm. It often goes dormant in winter, so ease off the water and wait rather than assuming it is dying. It is toxic to cats and dogs if chewed.
What it’s like to grow
Alocasia is demanding and quick to protest. Cold, dry air or erratic watering brings sudden leaf drop and yellowing, and low humidity invites spider mites and crispy edges. It wants warmth, steady moisture without sogginess, high humidity, and bright indirect light. A winter die-back is usually dormancy, not death, so do not drown it trying to revive it. It is toxic to cats and dogs. Best for an experienced grower who can meet its humidity needs, not a beginner.
What to expect
It rewards patience and steady attention. No sunny window? It also does fine under a clip-on grow light.
