What’s the purpose of the corm on a plant?
Certain plants have a swollen, underground plant stem called a “corm.” The purpose of this stem is to store nutrients, food that the plant will use at a future time. Nutrients stored in the corm during one growing season will help in the production of roots, leaves, and flowers for the next growing season. Difference Between Corms and Bulbs
