Duration: Perennial Nativity: Native Lifeform: Succulent General: Perennial succulent, forming from a basal rosette of thick, juicy, leaves, rosettes singular or few, 7-16 cm wide. Leaves: Succulent 3-9 cm long, glaucous and unarmed except for the short spines at the tips, blue-green in color, sometimes with a purplish tinge. Flowers: Borne on a thick, juicy stalk, forming paniculate cymes, white with red spots, star-shaped and 5-merous, with 5 petals and stamens, stamens can be reflexed from the flower center to expose the 5 conic styles. Fruits: Elongated capsules (follicle) with acuminate tips and numerous ovoid, reddish-brown, striate seeds. Ecology: Found on cliffs, in rocky crevices, and in mountain canyons, from 4,000-7,000 ft (1219-2134 m); flowers fall-winter. Notes: This species resembles a small and juicy Agave or aloe, is like a Sedum and is similar in appearance to many commercially grown succulents, except for the fantastic, star-shaped, white flowers with red spots. This plant is considered rare and has been reported only in Santa Cruz, Pima, and Cochise counties in Arizona, and is under protected status as salvage restricted. The name change for this species is relatively new, so look for it under Graptopetalum bartramii. Ethnobotany: Unknown Etymology: Echeveria is named for the 18th century Spanish botanist Atanasio Echeverria Codoy, while bartramii is named for John Bartram, an 18th century botanist and contemporary of Linnaeus.
