Description
Haworthiopsis 'Onigawara', formerly known as Haworthia 'Onigawara', is a slowly proliferous succulent that forms small rosettes of stiff, pointed leaves covered with gray tubercles. At first compact, the slow-growing rosettes become columnar with age. They can reach up to 3 inches (7.5 cm) in diameter. The leaves are dark green with varying grades of gray, black, and brown. They are triangular, recurved, and densely packed along the stem.
The flowers are small, white with green to brownish veins, and appear on slender, upright stalks in late spring and summer.
How to Grow and Care for Haworthiopsis 'Onigawara'
Light: H. 'Onigawara' thrives in semi-shaded positions. Brighter light conditions are needed to bring out the leaf coloration. Any window in your home or office will likely be appropriate for this succulent.
Soil: Use a commercial potting soil mix formulated for succulents or make your own.
Temperature: This plant likes warmer temperatures in summer but cooler in winter. H. 'Onigawara' can withstand temperatures as low as 30 °F (-1.1 °C). USDA Plant Hardiness Zones 10a to 11b, 30 to 50 °F (-1.1 to 10 °C).
Watering: In spring and fall, when the growth is most active, water H. 'Onigawara' thoroughly, then wait until the top of the soil dries out before watering again. Water your plant less during the winter when its growth slows down significantly. When this plant is mostly dormant during the hottest summer months, water it just enough to keep the leaves from shriveling.
Fertilizing: H. 'Onigawara' is a slow-growing plant that does not require much fertilizer. However, for optimum growth, fertilization is a good idea. Feed only with a dilute fertilizer and only during the active growing season. Avoid summer fertilizing as this succulent is in a 6- to 8-week rest period.
Repotting: When the plant has outgrown its container, repot it in the spring or early summer into a new, slightly larger pot with fresh soil.
Propagation: H. 'Onigawara' is mostly and easily grown by removing offsets from the mother plant. Remove offsets when they have started developing their roots. Spring is the best time to sow the seeds.
