How to Grow and Care
Cotyledons can be divided into two groups. One group consists of evergreen plants with a summer growing period. The other group is made up of deciduous plants, splendidly magnificent with large, solid fleshy stems. The second group grows during the winter, and sheds its leaves during the summer.

Cotyledons should be kept in a sunny position. Follow general succulent watering procedures. Be careful of over-watering when they are deciduous.
