Description
Dudleya virens is a succulent plant that forms clumps of rosettes of fleshy, usually green, sometimes glaucous leaves at the tips of branching caudices. The rosettes can reach up to 10 inches (25 cm) in diameter. Caudices are erect at first, later decumbent, and can grow up to 3.3 feet (1 m) and 1.2 inches (3 cm) in diameter. The leaves are linear to triangular-lanceolate, measuring up to 10 inches (25 cm) long and 1.2 inches (3 cm) wide. They are 2 to 5 times wider than thick.
The star-shaped flowers are white or somewhat marked with red and appear in spring.
Hardiness
USDA hardiness zones 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C).
How to Grow and Care
Most of the various habitats Dudleyas occupy become dry in summer. Therefore, cutting off water to Dudleyas in your garden during the summer is important. 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 following 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 re-established. Species that naturally grow on ocean bluffs are also salt-spray tolerant.
Dudleyas have their share of disease and pest problems. However, 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.
