Originating from eastern Asia, Colocasia esculenta, commonly known as Taro, is a delicate herbaceous perennial that thrives in moist, nutrient-rich soil and tropical environments. It flourishes in full sun to partial shade and is an excellent choice for planting along the edges of tree understories or as a decorative border. Consistent watering is essential, as the plant should not be allowed to dry out. While Taro is often cultivated as a houseplant, it requires more sunlight than many typical indoor plants. This species utilizes a corm for winter storage and can spread and be divided similarly to other perennials with storage organs. In various regions of Southeast Asia, where it is indigenous, the corm serves as a food source. The roots are characterized by their swollen stem tissue and distinctive ring-like scars, and Taro is thought to be one of the earliest domesticated plants.

Although Taro is not particularly noted for its flowers, it does produce some. Its most striking feature is its large, often vibrantly colored leaves, which contribute a lush texture to any landscape.

This plant is only suitable for hardiness zones 8-10. In colder zones, C. esculenta should be treated as an annual or its corms should be stored indoors from the first frost in the fall until late April in a cool, dry location maintained above 45°F. Alternatively, it can be grown in a pot and brought indoors during the same period.

For optimal growth of young plants or during propagation, it is recommended to plant them in a 5-gallon pot filled with rich soil and high moisture, placed in an area with full sun to partial shade.

Regarding pests and diseases, Taro is generally resilient and does not face significant issues from insects or diseases.

Colocasia esculenta Feature Summary

Attributes
Traditionally used medicinally for the treatment of digestive disorders.
India to Southern China and Sumatera
Poisonous until cooked. Poisons neutralized by thoroughly drying or cooking the plant or by steeping it in water. Taro root used in Southeastern Asian cuisine. Use salted water and boil for at least one hour. They are rich in vitamins A and C and they have more protein, phosphorus and calcium than a regular potato. Their starch is easily digested so it is often used in infant formulas as a first baby food.

Flowers
Rarely flowers. White or yellow spadix with a greenish or yellow spathe.

Leaves
Leaves are very large (up to 3 ft.). They are heart-shaped to arrow-shaped with prominent veins. The apex is obtuse while the base is somewhere between cordate and auriculate. The petiole comes out from the center of the leaf. There is a wide variety of colors and patterns.
