It is grown for foliage and is listed for USDA zones 10–11. ## Siting and Soil The breeder says caladiums prefer warmth and humidity, and advises against cold, soggy soil. Keep the soil moist; in cooler regions, containers can help the root zone warm and drain more readily. ## Maintenance Maintain even moisture through the warm growing season and avoid overly strong fertilizer that may burn the leaves. Proven Winners categorizes maintenance as easy and notes that deadheading is unnecessary.
