Crassula × perforata - Ivory Towers


Ivory Towers or Giant String of Buttons (Crassula × perforata) gets its name from its stacks of thick, joined leaf pairs skewered by a stem that grows up to 10" tall. Give it plenty of sunshine and its pistachio green leaves will take on a dark pink outline. Expect a tall bloom stalk lined with small, white flowers from this South African Crassula. It is distinguished from the other C. perforata varieties by its large size and the thick coating of farina that can give it a powdery blue appearance at times. As a soft succulent, it needs protection from frost in the winter. Planting tip: let this succulent go wild in a hanging pot for a beautiful trailing cascade.
