Alocasia 'Black Velvet' - Alocasia reginula
Light - Unlike some bigger Alocasia varieties, which you can train to handle full sun, Black Velvet thrives in dappled, bright but indirect light—similar to conditions found on the floor of a tropical jungle. A north or east-facing window works well, providing the morning light isn't too intense. Too little light often results in straggly, leggy stems, and the lush, dark foliage color won't excel.
Water - When caring for Alocasia Black Velvet, a cardinal rule is to make sure it's never left to sit in water. Overwatering and wet feet invariably result in root rot. Although they do like a decent amount of water in the growing season, it's best to water deeply, drain away any excess, and allow around 20 percent of the topsoil to dry before watering again. Placing the pot on a tray with water and pebbles will help prevent wet feet while still providing the humidity levels this plant enjoys. During the winter, watering is still advised, but much less frequently, and the soil can be allowed to dry out more in between.
