Cotyledon orbiculata 'Hakubi'
Cotyledon orbiculata 'Hakubi' is an evergreen, branching succulent up to 2 feet (60 cm) tall, with broad, fleshy, rounded leaves and leaf edges lined with red. Orange, bell-shaped flowers dangle from flower stalks that rise above the foliage in the summer.
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.
As succulents go, Cotyledons certainly are rewarding garden and indoor subjects, practically independent of irrigation in all but full desert conditions, though they cannot survive poor light or bad drainage in the wet.
Feed it once or twice during the growing season with a fertilizer specifically formulated for cactus and succulents (poor in nitrogen), including all micro nutrients and trace elements diluted to ½ the strength recommended on the label.
Though not spectacular, they are elegantly decorative and often interesting in shape. The inflorescences of the larger species often make fine components of dried arrangements in floral design… – See more at: How to Grow and Care for Cotyledon
