Family

Description
Huernia quinta is a variable succulent species with a tuft-like growth-form that grows to an average height of 7 cm. The flowers, which arise in groups of 4 or 5 from stem bases are attractively marked, creamy white, banded with dark red and with similar colouring on the reverse.
Stems are 4-(or 5)-angled, erect or ascending, often slightly twisted, grey-green, rather thick 7 cm tall, and about 2 cm in diameter, the persistent tubercles along the stem-angles end in a sharp dirty creamy white thorn up to 4 mm long
Environment
Huernias prefer bright light or partial shade. In nature, they grow underneath shrubs or other plants. Too much sun causes stems to develop protective reddish or purple pigmentation and can actually scald the stems. Too little light leads to weak, thin growth with decreased flower production.These plants grow best between 10 and 27 C. Protect them from freezing weather..
Huernias require a potting mix with excellent drainage. A succulent plant mix of 50 percent perlite, 25 percent vermicompost and 25 percent sand helps prevent rotting and over watering. Roots experience die back in cool-season dormancy, so plants grow best in shallow containers that allow the soil to dry out quickly. Using clay pots further helps soil from staying too wet. An underlayment of coarse gravel below the soil mix also improves drainage. In climates with damp cool summers, a layer of gravel between the plant and the soil mix also helps prevent the stems from staying too moist. Outdoor plantings do well in raised beds.
