Cotyledon orbiculata 'Mucronata' is an upright, sparingly-branched succulent up to 2 feet (60 cm) tall, with very attractive, dumpling-shaped leaves. They are upwardly inclined and are tightly overlapped with all parts of the leaves covered with a white powder, likened by some to "icing sugar" and have strongly undulating flat margins. In summer appear up to 1 foot (30 cm) tall inflorescences topped with dangling reddish-orange flowers.


USDA hardiness zone 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).

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 require a free-draining gritty mix and plenty of sun. They are tolerant of cool, frost-free conditions during the winter if kept dry. Some require pruning to maintain an attractive shape.

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