Description
Haworthiopsis coarctata, formerly known as Haworthia coarctata, is a succulent plant that forms clumps of stems packed with fleshy, dark green to brownish-green leaves with white rounded tubercles. Leaves are arranged in elongated rosettes, hiding up to 20 cm long stem. They are up to 7 cm long and up to 2 cm wide. The mature rosettes produce slender, up to 30 cm long flower stems that bear tubular white flowers with greenish-brown midrib from late spring to fall.
This species is native to South Africa (Eastern Cape), where it usually grows among rocks.
How to Grow and Care for Haworthiopsis coarctata
Light: H. coarctata thrives in semi-shaded positions. Brighter light conditions are needed to bring out the leaf coloration. Any window in your home or office is likely to be an appropriate setting for this succulent.
Soil: Use a commercial potting soil specially formulated for succulents or make your own well-draining potting mix.
Hardiness: This plant likes warmer temperatures in summer but cooler in winter. H. coarctata can withstand temperatures as low as -1.1 to 10 °C.
Watering: In spring and fall, when the growth is most active, water H. coarctata 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. During the hottest summer months, when this plant is mostly dormant, water just enough to keep the leaves from shriveling.
Fertilizing: H. coarctata is a slow-growing plant, and it does not require much fertilizer. 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 weeks 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.
