Plant Faqs
How much light does a Dark Star Alocasia need? (Bright, indirect light is best.) Is this plant toxic to pets? (Yes, like all Alocasia, it contains calcium oxalate crystals and is toxic if ingested.) How often should I water? (When the top inch of soil feels dry to the touch.)

Fleshy, healthy white roots; avoid signs of brown or mushy rot.
Soil Look
Dark, rich, well-draining potting mix with visible perlite or orchid bark particles.
