Overall, imperial taro is not only prized for its stunning leaves, but also for its significant contributions to cuisine and traditional medicine.
Cultivation Requirements
Cultivation requirements for Colocasia antiquorum include a preference for high humidity conditions and a temperature range of 21 – 28˚C (70 – 82˚F). Imperial taro is best suited for USDA zones 9 – 11 and thrives in slightly acidic soil with high organic matter content. Taro can be planted using bulbs or corms, with growth points facing upward. It requires regularly moist or wet soil and can tolerate occasional flooding. To ensure optimal growth, it is important to provide the plant with ideal growing conditions, such as a well-draining soil and regular fertilization. Additionally, leaves should be protected from scorching sunlight, and any damaged parts should be removed. In colder climates, foliage will naturally become yellow and die back in winter, and the bulbs can be dug out and stored in a cool, dry place during this period.
