About Taro (Arbi / Colocasia)

Taro (arbi) is a staple starchy corm used across Indian, Caribbean, Hawaiian, and African cuisines. The large decorative leaves make it a striking ornamental too. Grow from corms — never eat raw (the raw plant contains calcium oxalate crystals that must be destroyed by cooking).

Start corms indoors 8 weeks before last frost. Loves warmth, humidity, and consistently moist soil. Can grow in water or very wet soil. Harvest corms in fall when leaves yellow. Always cook thoroughly before eating. Can overwinter indoors as a houseplant.
