These are quite interesting for a crassula. Its numerous florets develops into a tidy circular half mound that will stay under 6". As it develops, small flowers appear at each center, making it appear as a perfect bouquet.
The symmetrical mound is balanced by its non-conforming individual florets. Its leaves are close together, forming little broken squares. The leaves have hidden woody branches that twist together.
This plant is not demanding and grows very slowly, making it a perfect windowsill plant.
