Adromischus trigynus

Adromischus trigynus, or Calico Hearts, is small succulent plant native to South Africa. It has alternate, nearly orbicular leaves up to 1½ inches (3.5 cm) long. They are convex both above and beneath, with conspicuous purple spots. Plants will reach 4-6 inches (10-15 cm) tall. Most plants are sold under the name Adromischus maculatus which differs in leaf shape and size. A. trigynus is an easy plant to grow and with the spotting makes it a very showy succulent.

Blooming Time: In late spring. In the greenhouse, small flowers emerge on 10 inch (25 cm) flower stalks. They are not particularly showy.

Culture: Adromischus trigynus need full sun, warm temperatures and a well-drained potting mix. In the greenhouse, we use a soil mix consisting of 2 parts course sand to 1 part loam to 1 part peat moss. Small gravel is added to insure good drainage. During the growing season (May-October), the plant are watered once a week. During this time, plants are fertilized only once with a balanced fertilizer diluted to ¼ the strength recommended on the label. During the winter months, the plants are moved into a cool room, which is kept at 48°F (9° C), and only watered only enough to keep the leaves from shriveling.

Propagation: Adromischus trigynus are propagated from leaf and stem cuttings anytime during the growing season.

Adromischus trigynus was featured as Plant of the Week June 11-17, 2004.
