Colocasia is a genus of tropical plants known for their large, heart-shaped leaves and edible corms. Commonly referred to as taro, these plants thrive in wet, marshy environments and are often cultivated in regions with warm climates. The corms are a staple food in many cultures and are rich in carbohydrates. These plants are also popular in ornamental gardening due to their striking foliage. Colocasia species can vary in size and color, with some having variegated or dark purple leaves. They are often used in landscaping to create lush, tropical aesthetics in gardens and parks.
