Grewia occidentalis or Lavender Starflower, a native of South Africa, is an evergreen shrub or small tree that will reach about 9 feet in nature. It makes a great specimen plant when planted in containers.
Blooming Time: Lavender flowers are axillary, 1-3 on slender peduncles from spring-fall. Individual flowers are 1½ inches across.
Culture: Grewia occidentalis need full sun and intermediate temperatures. We use a soil mix consisting of 2 parts peat moss to 2 parts loam to 1 part sand or perlite. The plant should be kept moist for optimum growth. Fertilize 3 times a year with an acid loving plant fertilizer. The plant tends to become chlorotic so an iron supplement is recommended at least once a year. When grown in containers the plant needs to be cut back after blooming to keep a desired shape.
Propagation: Grewia occidentalis is propagated by cutting of new growth in spring or by seed. Seed germinate in 14-21 days at 70° F.
Grewia occidentalis was featured as Plant of the Week November 16-22, 2001.
