Aeonium have a unique habit, with a Dr. Suess like personality when grown in pots. Rosettes of tricolor green, cream, and pink/red spatulate leaves radiate on sturdy stalks. If you prefer a more shrubby look, pinch back their heads in spring (root the rosettes in sand). It will take a while but plants will respond with a more compact habit. Grows 12-18" tall, maybe larger with years of growth behind them.
