Cotyledon orbiculata “Chalk Finger”



Cotyledon orbiculata “Chalk Finger”

Horticultural Data | Shipping & Availability | Top

Cotyledon orbiculata is also known as the Chalk Finger Aloe, no doubt due to its long finger-shaped leaves covered with a white chalk dusting. Cotyledon orbiculata’s velvety soft blue-green leaves spread slowly to form a low shrub or ground cover. In spring, Cotyledon sends up flower spikes which are topped with very pretty orange-red bell shaped flowers that are very attractive to hummingbirds.

Cotyledon orbiculata is very drought-tolerant once established, though it likes some water during its growing season in spring. This plant is a best watered from below to avoid washing off the attractive white, chalky dust which is actually a waxy protective leaf coating that helps in water retention.

Cotyledon orbiculata is an ideal plant for rock gardens, and also grows well in containers.

The plants themselves are poisonous to humans and domestic animals, especially sheep and goats, and the meat of animals killed by cotyledonosis remains toxic even after cooking. Poisoning may be acute or chronic, the latter due to the cumulative effect of the toxin.
