Description: Haworthia cymbiformisSN|14982]]SN|975]] var. obtusa is one of the innumerable morphological forms of the very variable Haworthia cymbiformisSN|975]]SN|975]] characterized by denser rosettes forming round clumps. It has peculiar bright green leaves that looks like molded glass. The leaves are thicker, obovate, with entire margins, and leaf-tips are rather obtuse or rounded and pellucid. It is vaguely reminiscent of Haworthia cooperiSN|975]]SN|14982]] var. truncata.
Habit: It is a spreading ground cover succulent forming dense mats of very succulents and juicy leaf-rosettes partially sunken into the soil, and reaching a diameter of 15 (or more) centimetres. In habitat only the leaf tips, which has a finger-tip-like appearance, protrude from the soil surface.
Roots: Superficial.
Stem: Stemless or shortly caulescent
Rosette: Stemless, dense, 20–25 leafed, 3-10 cm in diameter.
Leaves: Succulent, soft, very juicy, obovate with entire margins, and leaf-tips are rather obtuse or rounded and pellucid..
Flowers: Relatively inconspicuous whitish/greenish with a light pinkish-brown keel, peduncle simple, 15 cm long; raceme lax, 15 long; lower pedicels 4-6 mm long; bracts small, ovate; perianth 2 cm long; segments nearly as long as the tube.
Blooming season: Spring to summer.
Chromosome number: n = 7

Cultivation and Propagation: Haworthia are of easy cultivation and relatively low maintenance, which makes them a good houseplant, and can be an excellent subject for the beginning succulentophile (they can grow easily on window sills, verandas and in miniature succulent gardens where they are happy to share their habitat with other smaller succulent plants, or in outdoor rockeries). Haworthias are winter growers and are dormant in the hottest summer months.
Growth rate: They are relatively fast-growing plants that offsets freely to form small clusters quickly.
Soil: They are tolerant of a wide range of soils and habitats, but prefer a very porous potting mix to increase drainage. A non-acid soil is ideal. You can grow a plant in a 10-15 cm pot for years and have perfectly happy plants. For best results, use a shallow pot.
Exposition: The plant needs light shade to shade, but will take full sun part of the day. (with some sun exposure the leaf develops a nice reddish tint and remains compact).
Watering: During the hot summer months, the soil should be kept moist but not overly wet. During the winter months, water only when the soil becomes completely dry. Wet soil quickly causes root and stem rot, especially during chilly winter months. No water should ever be allowed to stand around the roots. Low ambient humidity is always needed.
Fertilization: The plants are fertilized only once during the growing season with a balanced fertilizer diluted to ½ the recommended strength.
Hardiness: Although the plant will survive mild frost if kept dry (hardy as low as -5° C) it should be protected from severe cold and prolonged frost conditions.
Rot: Rot is only a minor problem with Haworthia if the plants are watered and “aired” correctly. If they are not, fungicides won't help all that much. Care must be given in watering, keeping them warm and wet while growing, and cooler and dry when dormant.
Remarks: Haworthias are best planted in a shaded and airy part of the greenhouse, and not too close to the glass roof or sides of the house as the plants can overheat during hot spells.
Propagation: Haworthia are easily propagated by the removal of offshoots or by leaf cuttings in spring or summer. To propagate by leaf cuttings, remove a leaf and let it lie for about one month, giving the wound time to heal. Then lay the leaf on its side with the basal part buried in the soil. This leaf should root within a month or two, and small plants will form at the leaf base. They can also be grown from seed.
