Dudleya brittonii (Giant Chalk Dudleya) - 1000 Seeds - Bulk

Dudleya brittonii, commonly known as Giant Chalk Dudleya or Britton's Dudleya, is a striking succulent native to coastal northern Baja California, Mexico. It is especially prized for its large, sculptural rosettes and distinctive white to silver-gray foliage.

The leaves of the characteristic chalky form are covered with a heavy natural wax coating that gives the plant its brilliant, almost powder-white appearance and helps protect the foliage from intense sunlight. Mature rosettes can reach approximately 12–18 inches across, creating an impressive architectural specimen.

In late winter through spring, plants produce tall reddish-pink flower stalks carrying clusters of pale yellow flowers, creating a dramatic contrast against the silvery foliage.

This listing is intended for professional growers and customers seeking dependable propagation material.

Germination & Cultivation

Dudleya brittonii can be propagated from seed in a fine, well-draining propagation medium. Because the seeds are very small, they should be surface sown or only very lightly covered. Maintain controlled moisture during germination without allowing the growing medium to remain excessively wet.

Established plants require excellent drainage and are well adapted to dry conditions. In hotter climates, some protection from intense afternoon sun can be beneficial.

Its exceptionally chalky foliage, large rosette form, drought tolerance, and dramatic flower stalks make Giant Chalk Dudleya an outstanding species for succulent production, specialty collections, containers, rock gardens, and drought-tolerant landscapes.
