Gardeners' Notes:

According to Steve McCabe, the person who officially published the description of Dudleya gnoma (Madroсo 44: 49 1997), all plants which were Dudleya greenei are now D. gnoma. In contrast, Urs Eggli, in his book “Illustrated Encyclopedia of Succulents - Crassulaceae," states that the two are separate species and classifies them as such. According to Eggli, "D. gnoma differs from D. greenei by the smaller rosettes with shorter triangular to triangular-ovate leaves, smaller flowers and shorter pedicels."

In addition McCabe states, in the Dudleya Issue of the Castus & Succulent Society Journal, Vol. 76, No. 5, p.276, that "plants that are cuttings of Dudleya greenei 'White Sprite' are now known as Dudleya gnoma 'White Sprite.' Other collections of this species that are not cutti. read more ngs of Moran's original plant are simply known as Dudleya gnoma." Reid Moran was the original discoverer of what is now known as D. gnoma. It is difficult, if not impossible, to know which plants in the DG PlantFiles are or came from cuttings of D. gnoma ‘White Sprite’ and which did not.

Because of this current confusion, Dave’s Garden is keeping the two species separate and will denote 'White Sprite’ as a synonym of D. gnoma. As these issues are resolved we will change our PlantFiles entries for each plant.

I Have this plant growing in a pot. The winters here get to wet and cold for it to be in the ground. Seems to do great overwintered in the greenhouse.

Dudleya: A Field Guide

In a warm climate, succulent Dudleya can be either a useful ground cover (if you plant one of its branching, spreading species) or a dramatic specimen plant with pointed leaves forming a tight rosette.

Beware: Dudleyas will wither in dry summer months, but that is no reason to water them. In fact, it’s best to leave these evergreen perennials succulents alone. Allow them to recover naturally (and rather theatrically) in winter when rainfall occurs spontaneously. Because of their seasonal proclivities and dormancy, interplant Dudleyas with companions that will perform during their low periods.

With blue, gray, or green foliage (and a chalky wax on their epidermis to protect the plants from sun damage), Dudleya is an attractive choice either in a garden bed or a container garden. In a container, plant it in sandy or gravelly soil (a cactus mix is best) and choose other low-water companions.

Recent Articles

Dudleya have been getting some attention in the press lately due to an unfortunate run of poaching incidents along our California coastlines. But Dudleya have been studied and admired for decades by native plant enthusiasts and succulent enthusiasts. Their brilliant white farina and their ability to survive in tough conditions along our California coastline are just a few things that draw admiration for Dudleya.

Background

Dudleya is a genus of succulents endemic (only native here!) to California and Mexico. In their natural habitat, they cling to rocky outcrops and bluffs along the coast. They are very slow growing in nature, so if you see a large clump, it may be more than 100+ years old. For this reason, their common name is Live-Forever.

Landscaping with Dudleya

In the garden, Dudleya offer large rosettes that stand out due to their white powder called farina -- which protects them from harsh weather conditions such as wind and sun. When in bloom, their long red or pink flower stalks shoot up yellow and pink flowers and offer pollen to local wildlife, making this plant a stunning specimen in any succulent garden.

To achieve a natural look, plant a single Dudleya brittonii next to a rock and tilt it towards the point of view of the passerby. This will allow excess water to drain off of the leaves and provide support for your new garden specimen. All of our Dudleya are grown by seed, so you may see differences in each plant due to genetic diversity.

Varieties

There are over 40 varieties of Dudleya found in nature. We cultivate a few different types of Dudleya at Succulent Gardens, and generally have them available in the summer months in 1 gallon and 2 gallon sizes. This year's healthy crop will include Dudleya brittonii (Giant Chalk Live-Forever) and Dudleya hassei hybrid (Catalina Island Live-Forever). We are currently working on increasing our numbers of Dudleya found locally in California including: Dudleya lanceolata (Lanceleaf Live-Forever), Dudleya farinosa (Bluff Lettuce), and Dudleya hybrids.

Dudleya Care

Dudleya should be planted in full sun on the coast and protected from afternoon sun in inland gardens. Dudleya should be provided with excellent drainage to prevent rotting. Deeply soak plants when soil approaches dryness. In summer, avoid overhead irrigation and water just once a month. You can expect plants to look smaller and shriveled up in summer months, but will perk up with the cooler temperatures and more water in winter and spring.

In spring, large flower stalks will rise above the rosettes which can be pruned when dried out or if aphids appear. Save the small dust-like seeds and sprinkle over flats of moist soil to propagate.
