Description
Haworthia arachnoidea is a small succulent with a usually solitary rosette since it produces offsets very slowly. The size of the rosette can reach up to 7 inches (17.5 cm) in diameter. Leaves are dark green with no translucent area and tips, occasionally drying and forming a protective cover for the rosette. The leaf's margins and keels are with translucent spines. This plant is sometimes confused with its relative Haworthia decipiens.
Hardiness
USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
Haworthias are one of the easiest succulents to care for, which makes them popular houseplants. They are great plants for beginners.
Although some species can grow in full, bright sun, most Haworthias live in more sheltered spots, and they are adapted to thrive in partial shade. In habitat, they tend to grow under bushes and rock overhangs. This adaptation makes them well suited to lower light conditions found in homes and offices.
All Haworthia species do not like their roots to remain wet for prolonged periods, so their potting soil should be well-drained. In habitat, they are found growing in sandy soils in rocky areas. Use a commercial succulent soil or make your own well-draining soil mix.
These succulents are very tolerant of underwatering, but overwatering can quickly lead to rotting. From spring to fall, water thoroughly, then wait until the top of the soil dries out before watering again. During the winter rest period, water just enough to keep leaves from shriveling. If you use saucers, empty any standing water promptly.
