Haworthia turgida aka Windowpane Haworthia

Haworthia turgida is a small succulent with thick, swollen leaves. It belongs to the Asphodelaceae family and lives for many years. Its home lies in South Africa's Western Cape. Its range runs from Swellendam to Riversdale. Kew places it in a subtropical climate. Wild plants grow on limestone hills and slate. Thorn bushes shade them from much of the strong sun.

The plant forms low rosettes with almost no visible stem. Each holds 20 to 40 leaves packed close together. Most rosettes span 0.16–0.21 feet [0.05–0.065 metres]. Some reach about 0.33 feet [0.10 metres] across. New shoots grow from the base and build dense, rounded clumps. Plants differ in leaf shape, size, markings, and growth habit. The species forms new shoots freely and builds clusters fairly fast.

The fleshy leaves range from broad, tapering shapes to long triangles. Each measures about 0.03–0.13 feet [0.01–0.04 metres] long. Leaves can be almost as thick as they are wide. Their tips may bend back or appear slightly flattened. The smooth upper surface lets some light pass through. Grey-green or yellow-green leaves bear three to seven green lengthwise lines. Pale flecks often break up the green surface. The edges and keel may be smooth or lightly spined. Cold, strong light, or severe dryness can turn leaves burgundy.

Small flowers appear in spring on thin, upright stalks. These reach about 0.49–0.66 feet [0.15–0.20 metres] tall. The narrow, tube-shaped flowers look brownish white, with darker veins. A stalk may carry about 20 to 30 blooms. The leaves and clumping form give the plant its main garden value. It suits windowsills, verandas, small succulent displays, and outdoor rock gardens. Its small rosettes fit among other small succulents.

In cultivation, give it shade or light shade. It can also take direct sun for part of the day. Some sun brings red tones and helps keep growth compact. Use a loose potting mix that lets water drain well. The species account favours soil that is not acidic. A shallow pot suits its growth. Plants can remain in pots 0.33–0.49 feet [0.10–0.15 metres] wide for years. The account describes winter growth and rest during the hottest summer weather. In hot months, keep the soil moist rather than soaked.
