Dudleya brittonii "Green Form" (Giant Chalk Dudleya) A solitary or low slowly-clumping succulent with beautiful 12 to 18 inch wide rosette of flat light green leaves surrounding a thick basal stem. Stout 1 to 2 foot long spikes arch upward and blush red as the clusters of yellow flowers begin to open in late spring to early summer. Plant in a well-drained soil in full sun along the coast but looks best with part sun in hotter inland locations. This plant can tolerate garden conditions better than many other species of Dudleya but it is still best if one keeps this plant dry in summer months and particularly avoid overhead irrigation during this time – this plant tolerates going without irrigation in summer in coastal gardens but can look better with a careful infrequent watering below the foliage. Hardy to around 15 F or slightly below. This is a great plant for the rock garden, a crack in a rock or wall or as a container specimen. This species is native to coastal areas of the Pacific side of Baja California between Tijuana & Ensenada and on Isla Todos Santos where it grows on cliffs and hilly areas in lava rock and other very porous soils. Both green and chalky white forms can be found growing together in habitat and seed from the white-leaf forms yields both as well. We also grow the whlte-leaf form which we just list as Dudleya brittoni. The genus was named for William R. Dudley (1849-1911) a botanist at Stanford University and the specific epithet honors Nathaniel Lord Britton (1859-1934), botanist and first Director of the New York Botanical Garden. Dr. Britton is also famous for his collaboration with Joseph Nelson Rose of the Carnegie Institute on The Cactaceae, a four-volume work started in 1906 and published in 1924. The coating that gives the white-leaf form this look is a wax-like substance on the surface of the cuticle that gives the leaves one of the highest ultraviolet reflectivity of any plant. This plant was first described by Dr. Donald A. Johansen, a Stanford Botanist, in 1933 in the Cactus and Succulent Journal of American (4:311) and an image graced the cover of the July 1973 issue of the California Horticultural Journal (Vol. 34 No. 3), the predecessor to Pacific Horticulture. Our plants from seed off of a Huntington Botanic Garden collection (HBG 71521) that was from an anonymous seed collection made at Rancho La Salina, between Tijuana & Ensenada.
The information about Dudleya brittonii "Green Form" displayed on this web page is based on our research conducted in the nursery's horticultural library and from reliable online resources. We also include observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments we receive from others and welcome hearing from anyone with additional information, particularly if they can share cultural information that would aid others in growing this plant. |
