How to Grow and Care for Colocasia Redemption

Colocasia esculenta ‘Redemption’ is a highly sought-after ornamental plant with a dramatic, tropical aesthetic. Its immense visual appeal stems from its bold foliage, which provides a striking color contrast rarely seen in garden exotics. Its impressive size and vigor make it a stunning focal point, whether planted in the ground or showcased in large containers. It creates a deep, rich backdrop, making it a favorite for complementing brighter flowering plants.

Identifying Features of Redemption

The distinguishing feature of ‘Redemption’ is the unique coloration of its massive, heart-shaped leaves, which can reach four feet in height and width. The leaves emerge dark, almost jet-black, intensifying to a deep blackish-purple as the foliage matures and is exposed to sunlight. This dark canvas is dramatically offset by a central blotch and radiating veins of vivid, neon pink. The pink is most intense near the center, appearing to bleed out along the corrugated veins toward the leaf margins. The petioles, or leaf stems, also carry a hint of bright pink or red, enhancing the overall visual impact.

Optimal Growing Conditions

Light Requirements

Achieving the deepest black and most vibrant pink coloration in ‘Redemption’ requires careful light placement. The plant thrives in conditions ranging from full sun to partial shade. Adequate light is necessary to saturate the foliage with its characteristic dark pigment. In regions with intense summer heat, however, a location that receives afternoon shade is beneficial to prevent the large leaves from scorching.

Water Needs

As a member of the Colocasia genus, ‘Redemption’ is a moisture-loving plant that requires a consistently high water supply throughout its active growing season. The soil should be kept continuously moist, though not waterlogged, mimicking its native tropical habitat. This makes it an excellent choice for bog gardens, rain gardens, or planting near water features such as ponds. For container gardening, the high water demand means daily watering may be necessary during warm, dry periods to prevent the soil from drying out.

Soil and Feeding

To support its rapid growth and large foliage, ‘Redemption’ requires a rich, organically enhanced soil that drains well but still retains moisture. Amending the planting area with compost or other organic matter provides the necessary structure and nutrients. This cultivar is a heavy feeder and requires regular fertilization during the spring and summer months. Applying a balanced, water-soluble or slow-release liquid fertilizer every few weeks will promote lush foliage and growth.

Preparing for Winter Dormancy

As a tropical perennial hardy only in USDA zones 8 to 11, ‘Redemption’ requires special preparation to survive winter in temperate climates. The process begins after the first light frost, which signals the end of the active growing period and causes the foliage to die back. Once the leaves have collapsed, trim the remaining foliage down to a few inches above the soil line.

The corm, or underground storage organ, must then be dug up and removed from the soil. After brushing away excess dirt, the corm should be allowed to dry completely in a warm location for one to two weeks to encourage full dormancy. Proper storage is in a cool, dry location where the temperature remains consistently above 45°F (7°C), ideally between 41°F and 50°F. The corms can be placed in a breathable medium, such as peat moss, dry sand, or sawdust, and stored in a paper bag or cardboard box until they can be replanted the following spring.
