Orostachys aggregata

(syn: Sedum aggregeatum) Native to seaside rocky areas around Honshu, Japan, this easy-to-grow, rosetted succulent forms low clumps of fleshy-green, rubbery foliage. The main rosettes offset well via short 1″-2″ white stolons. In fall, the clumps are topped with bizarre little flower heads that resemble erupting volcanos. Orostachys are easy-to-grow gems for the well-drained rock garden…expect a 1′ wide mass in 2-3 years.
