Aeonium haworthii or Pinwheel, a native of the Canary Islands, is one of the most commonly grown Aeoniums. In nature they will reach they will reach 2 feet in height with a 2-foot spread, but in containers they only reach 1 foot in height with an 18-inch spread.
Blooming Time: Spring. The inflorescence is 4-5 inches tall and flowers are creamy-yellow.
Culture: Aeonium haworthii need full sun and a well-drained soil mix. We use a soil mix consisting of 1 part peat moss to 2 parts sand to 1 part limestone chips. The plant starts new growth in late summer and should be well watered and allowed to dry before watering again. Repotting should also be done at this time. In late spring, watering should be reduced to allow the plants to harden off for the hot summer months. During the summer, water only enough to keep the leaves from wilting. During the winter month the temperatures should not fall below 50° F.
Propagation: Aeonium haworthii is propagated by cutting in late summer as new growth begins.
Aeonium haworthii was featured as Plant of the Week August 3-9, 2001.
