Dudleya is a small genus of rosette-forming succulent plants form California and Mexico. Grown for their lovely formation, most Dudleyas are strikingly beautiful when grown in landscapes or as specimen plants. A Dudleya is usually characterized by a green or silvery-white, succulent leaves that grow on a short stem to form a small rosette. Most species remain solitary whereas only a few of them branch. Flowers of white, red or yellow color appear in late winter or early spring from the bottom, rarely from the center, of the rosette.
How to Grow Dudleya
Most species of Dudleya look similar to Echeveria which is another large genus of succulent plants but recently Dudleyas have been classified separately because of their flowering habit and growth pattern. They are winter-loving plants that usually go dormant is summer. They are quite hardy and drought resistant plants too thus making a good choice for rock gardens. When grown in landscape, most species of Dudleya tend to form thick clusters of small rosettes that add a dramatic look to the landscapes. Though, they can be grown as specimen plants, the best place to grow Dudleya plants is a tough landscape spot where very few plants can survive. Dudleyas would require good sunlight, a well-drained soil and small amount of water in winter (and barely sufficient moisture in summer). When provided with a congenial environment, Dudleya plants can grow for decades. For this reason, they are also known as ‘Live-Forever’.
Popular species of Dudleya include:
D. brittonii (Chalk Dudleya): A large rosette-forming plant with silvery-white leaves. Perfect for landscape as well as specimen plant Dudleya brittonii remains solitary and produces spectacular yellow flowers.
D. caespitosa (Sand Lettuce): A low-growing succulent plant that usually grows in to thick clusters. Yellow flowers appear in beautiful contrast to pale-green or silvery-white foliage.
D. pulverulenta (Chalk Live Forever): Another large and solitary plant known for its beautiful foliage. It is quite hardy plant and can be grown as ornamental plant in landscape and rockeries.
