Colocasia esculenta var. antiquorum 'Illustris'

Light Requirements: Prefers partial shade to full sun. While it can tolerate full sun, partial shade is ideal, especially in hotter climates, to prevent leaf scorch and maintain vibrant foliage color.

Soil Requirements: Thrives in moist, well-draining soil. It prefers slightly acidic to neutral pH (6.0-7.0). Incorporating organic matter such as compost can improve soil fertility and structure. It can tolerate wet soils and is suitable for bog gardens and areas with poor drainage.

Watering: Requires regular watering to keep the soil consistently moist. Water deeply to ensure the root zone is adequately hydrated. This plant prefers consistently wet soil conditions, making it an excellent choice for water gardens or along pond edges.

Temperature and Humidity: Hardy in USDA zones 8-11. Prefers warm temperatures and high humidity. Protect from frost and cold winds. In cooler climates, consider growing it as an annual or bringing it indoors during the winter months.

Fertilization: Apply a balanced, slow-release fertilizer in early spring and again in mid-summer to support healthy growth. An additional application of compost or well-rotted manure can enhance soil fertility. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of overall plant health.

Pruning: Remove any dead or damaged leaves throughout the growing season to maintain a tidy appearance. Cut back the foliage after the first frost in colder climates if grown as a perennial, or before bringing it indoors for winter storage.

Pests and Problems: Generally pest-resistant but can occasionally attract spider mites, aphids, and snails. Ensure good air circulation to prevent fungal diseases. If pests are detected, treat with insecticidal soap or neem oil. Keep an eye out for root rot in poorly draining soils.
