Description: Haworthia 'Hakuma' is a fascinating Japanese hybrid with small triangular rasp-like crystalline leaves with tubercles, turning pinkish to brownish-red in good light. The toothy texture of the silver leaves is reminiscent of Haworthia emelyae var. major. The prize of this plant is due not only to its indisputable beauty but also for being very slow growing (Slower than an Ariocarpus fissuratusSN|2114]]SN|2114]]!). This plant remain for a very long time solitary but may produce a few basal shoots when very old (if any at all).

Hakuma) Photo by: Valentino Vallicelli 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. Needs a deep pot to accommodate the long, thick, contractile roots.
Watering Needs: It needs regular water, but do not water again until dry. Also, it is a species that is dormant in the winter and requires very little water (maybe even none) during the cold months.
Frost Tolerance: Light frost protection required. Minimum of 5ºC for safe growing (but hardy up to -5°C or less.)
Sun Exposure: Requires light shade to bright light (protect from strong midday sun). In shade the body colour will remain mostly green, while full sun will darken and give it a rich pink-red body colour. Can be sunburned if moved from shade/greenhouse into full sun too quickly. The amount of sunlight it can withstand without scorching depends upon the how hot it becomes in the summer in the location in which it is planted. It will have more colour if it receives more light. During the spring it may be able to take full sun until the heat arrives at the end of spring. In an area that has hot afternoon sun, it may be able to take full morning sun, but requires afternoon shade or afternoon light shade.
Propagation: Offsets that appear at the base between the leaves; leave them attached to form a cluster, or wait until they are 1/3 the size of the parent and then detach and plant.
