Variegated String of Buttons
Crassula perforata var. variegata
These are vertically oriented strings of triangular leaves with yellow and green coloring. The pink edges come with full sun, but they can handle a lot less than full sun too. They will grow to almost 2 feet tall, and then start to dip over.
Hardy to about 22F, we find with a hard freeze you can see some tip damage which will then cause the plant to start branching vigorously, so it’s all good.
South African.
Tiny yellow blooms are not particularly interesting, unless you get in really close with your macro lens. Fascinating!
