Dudleya brittonii, commonly known as Britton’s dudleya, Britton’s liveforever, or giant chalk dudleya, is a succulent plant native to the rocky cliffs and slopes of northern Baja California, Mexico. This species is notable for its striking rosettes and its ability to thrive in harsh, arid environments. Dudleya brittonii typically forms a clustered rosette atop a large reddish-purple peduncle. It has two forms, green and white, with the white form covered in a chalky epicuticular wax that reflects light and helps reduce water loss. The green form is more widespread and lacks the waxy coating. Both forms have yellow leaves, and during the flowering season, they produce a bright green calyx about 5 mm long with acute, long-lanceolate segments. The petals are hyaline to pale white, with the keel imbued in yellow, offering a subtle floral display.

Britton’s dudleya is valued for its sculptural form and low water requirements, making it an excellent choice for rock gardens, succulent collections, and as a potted specimen. It has earned the Royal Horticultural Society’s Award of Garden Merit, highlighting its desirability for gardeners. While it can tolerate some shade, it flourishes in full sun and requires well-draining soil to prevent root rot. During the summer months, it can be placed outdoors in a sheltered, sunny spot, but in temperate climates, it is often grown under glass to protect it from excessive moisture and cold. It is among the largest of the Dudleya species, adding a dramatic presence to any succulent display. Care should be taken to avoid overwatering, as this can lead to fungal diseases and root rot.CC BY-SA 4.0
