How to identify Giant chalk dudleya (Dudleya brittonii)

Giant chalk dudleya presents with a striking rosette of chalky-white leaves spanning 12 to 18 inches (30 to 45 cm) in diameter. The leaves radiate from a robust basal stem, and the plant may occasionally exhibit a low, slowly-expanding cluster formation. Floral interest is added with stout, silvery-white flower spikes reaching 1 to 2 feet (30 to 60 cm) in height that arch upward. These spikes turn a reddish hue when the clusters of yellow blossoms start to open, typically in the late spring to early summer. The plant’s leaf surface is coated with a wax-like substance, contributing to a notable ultraviolet reflectivity.

This species grows best in cultivation when planted on rock walls or slopes. If it is planted facing the sky, it's more likely to fill with rain and die from root rot. This plant's leaves have a notable waxy coating, and it is considered especially susceptible to aphid infestation. Aphids cause the chalk Lettuce's leaves to have deformities.
