Adromischus triflorus - Calico Hearts

Commonly Known as: Calico Hearts

Care Information: Many species are easy to grow in any free-draining, gritty compost. Their compact habit allows a collection to be maintained in a small space, and they grow well on any sunny window ledge or the top shelf of the greenhouse. Water mostly from spring to fall and let them dry out between waterings. Adromischus tolerates cool, frost-free conditions during the winter if kept dry. It is as well to keep water off the foliage during the winter. Mealybugs and vine weevils can be discouraged with a systemic insecticide.

Adromischus can be propagated from a single leaf, which should be placed against the pot's side so that the stem ends touch the compost. Some species drop their leaves easily, and although each leaf will form a new plant, growing a large specimen can be challenging. In other cases, leaves for propagation must be carefully detached with a sharp knife.
