Planting Tips

Colocasias, grown as a food source in tropical areas of the world, are considered ornamentals in our temperate climate.  They add a coarse texture to the garden that is hard to achieve otherwise. With all that foliage to support, they are heavy feeders. They are also heat-lovers, and therefore slow to get started in the spring, but once the weather gets hot and the humidity rises, you can almost see their large, coarsely-textured leaves expanding. They will tolerate wet conditions, but may be more winter-hardy in soils with better drainage.  A good layer of mulch will help them survive our winters.
