Not all succulents are native to California, but the Giant Chalk Dudleya is!
Did you know that the majority of the succulents you see in stores are not native to California? Most succulents are actually native to South Africa. We are in luck, however, as our incredibly diverse ecosystem here in CA does have one succulent genus - the Dudleyas! These incredible species have evolved a special photosynthetic pathway that helps them conserve water. Unlike most plants, Dudleyas take in carbon dioxide at night, and keep their leaf pores tightly closed during the day. This helps them reduce water loss by as much as 90%!
One of the most striking and easy to grow species is Dudleya brittonii, or the Giant Chalk Dudleya. This slowly-clumping succulent forms a 12" to 18" wide rosette of chalky-white leaves that arch upwards 1 to 2 feet. The wax-like coating that creates this plant’s chalky appearance also gives the leaves one of the highest ultraviolet reflectivity of any plant! Clusters of yellow flowers appear in late spring on stalks above the plant. Do not worry about watering this plant in the summer, as it likes to be dry and does not like overhead irrigation. Plant in well-draining soil, and in part sun in hot inland locations. Giant Chalk Dudleya would be great as an accent in any garden!
