Dudleya gnoma is a rare, compact succulent that grows from a caudex topped with clumps of leaf rosettes, up to 2 inches (5 cm) in diameter, of up to 20 small leaves. The fleshy, triangular to triangular-ovate leaves are green, red-tinged, or white with a waxy powdery coating of exudate. Each leaf is up to 1 inch (2.5 cm) long and up to 0.5 inches (1.3 cm) wide. It produces an inflorescence up to 5.2 inches (13 cm) tall and studded with small, triangular leaves. It bears up to 10 flowers. They are pale to bright yellow, sometimes orange and up to 0.4 inches (1 cm) long.
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Most of the myriad habitats Dudleyas occupy become dry in summer. Therefore, it is important to cut off water to Dudleyas in your garden during the summer. Plants grown in sandy soils or containers are exceptions. They will accept infrequent summer watering as long as the soil drains well. The onset of fall or winter rains reawakens Dudleyas from drought-induced dormancy. Their shriveled leaves plump up quickly, growth resumes, and flowering occurs during the next spring or summer. These plants are amazingly resilient. If a portion of a colony sloughs off a cliff face or is uprooted by a burrowing animal, it can persist for months until soil contact is reestablished. Species that naturally grow on ocean bluffs are also salt-spray tolerant.
Dudleyas have their share of disease and pest problems. If you can prevent Argentine Ants from introducing mealybugs or aphids to your Dudleyas, they will be healthier. Mealybugs nestle in the deep recesses of the leaves, and their feeding weakens the plants.
