Haworthia margaritifera or Pearl Plant, a native of South Africa, is one of the largest species of Haworthia. The dark green leaves with white tubercles will reach 6 inches across and 4 inches tall in pots.
Blooming Time: Spring. Flowers are small, white and not particularly showy.
Culture: Haworthia margaritifera need full sun to light shade, warm temperatures and a well-drained soil mix. We use a soil mix consisting of 2 parts loam to 2 parts course sand. Allow the soil to dry in between waterings in the growing season. Fertilize monthly with a balanced fertilizer diluted to ½ the strength recommended on the label. In the winter months reduce watering and do not fertilize. Repot only when the plant has outgrown its pot. Clay pots are best.
Propagation: Haworthia margaritifera are propagated by removal of offset from the main plant.
Haworthia margaritifera was featured as Plant of the Week June 1-7, 2001.
