Alocasia (Alocasia macrorrhizos), commonly called Giant Taro or Elephant Ear, is a bold tropical foliage plant grown for its huge, glossy, arrow-shaped leaves held upright on sturdy stems. It creates an instant jungle-like statement in gardens, courtyards and large pots, thriving in the warmth and humidity of the Indian monsoon. Fast-growing in the warm season, it can reach impressive size given space, moisture and rich soil. While cultivated forms are ornamental, the species is also a traditional food crop in parts of Asia after thorough cooking. Its dramatic foliage makes it a favourite architectural accent.
