Description

Huernia humilis is a small compact succulent with beautiful flowers highlighted by dramatic colors, with a fleshy, rose, donut-shaped annulus in the center, darker than the yellow lobes with small maroon spots. The tube is maroon inside and smooth at the mouth. The flowers are star-shaped, up to 1.2 inches (3 cm) in diameter. The short stems are green, glaucous green or grayish and usually with maroon markings, branching from the base, acutely 4- or 5-angled, tapering to the apex in a pyramidal shape or globose, nearly erect and stout. They are up to 3 inches (7.5 cm) long and 0.8 inches (2 cm) thick, excluding the teeth.

Hardiness

USDA hardiness zone 10b to 11b: from 35 °F (+1.7 °C) to 50 °F (+10 °C).

How to Grow and Care

Huernias require a potting mix with excellent drainage. A succulent plant mix of 50 percent pumice or perlite, 25 percent peat or organic mulch, and 25 percent sand helps prevent rotting and overwatering. Roots experience dieback in cool-season dormancy, so plants grow best in shallow containers that allow the soil to dry out quickly. Using clay pots further helps the 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. 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. Huernias grow best between 50 and 80 °F (10 and 27 °C). Protect them from freezing weather.
