Native to Madagascar and South Africa, this spine covered succulent only has leaves at the very top. I've had one for over 8 years and it hasn't bloomed yet. But this is the time of year they bloom and these frangipani-like flowers in white are nestle among the leaves. Apparently the trunks need to be at least 3' before they bloom which probably explains why mine haven't yet. It's almost there and these are slow growers.
