Colocasia esculenta – Coffee Cups
This is one of my all-time favorite plants. The cupped foliage will collect rainwater until there is enough water to bend the stem and pour the water out. It is really cool and will appeal to kids of all ages. Colocasia are great tropical plants suited to be grown as annuals in cold winter climates and perennials in warm winter climates. Some Colocasia tend to spread by runners, while others remain as a clump. Coffee Cups is a clumper.

Maintenance Notes
According to the Humane Society of America Colocasia plants can be toxic to pets. This is means that the plants are generally identified as having the capability for producing a toxic reaction.
This plant is not edible and can be harmful to humans if ingested.
These are durable plants that will perform best with moist to wet soil, but can tolerate some drought stress. Drought stress will negatively affect the appearance of the plant.
Colocasia form tubers and these tubers can be stored for replanting in the spring. To dig and store tubers follow these directions. First, allow frost to kill the top of the plant then cut back the stems and dig the tubers. Wash off any soil and then allow the tubers to dry. Wrap dry tubers in newspapers or pack them in peat moss. Label each tuber or group of tubers so you know what they are come spring. Store tubers in a dark, cool (35 to 45 F) place. Do not allow tubers to freeze.
