The once traditional Aeonium arboreum, with round, dense rosettes of slightly serrate, olive green leaves has become less popular than its more colorful varieties that have become more available over the years. ‘Atropurpureum’ has rich purplish brown foliage. ‘Zwartkop’ is even darker and stays more compact. Long and sometimes unkempt clusters of tiny yellow flowers that bloom in spring or summer are not much to look at against green foliage, but contrast nicely against dark foliage. Larger plants can get to three feet tall and wide, with foliar rosettes wider than six inches.

Like many succulents, Aeonium arboreum is so easy to propagate from cuttings, that small pieces that need to be pruned from established plants can be plugged into the garden wherever more of the same plants are desired. New cuttings like to be watered until they develop roots. Established plants are a bit happier with occasional watering, but can survive neglect just fine. After all, they are native to similar climates in the Mediterranean and northern Africa.
