    One of a handful of deciduous spiny stem succulents from West Africa that become large, chunky-stemmed, multi-branched shrubs after many years. The species name is misleading (there may be one main stipular spine, but usually also two more smaller ones).

    Very seasonal (summer-fall) growth pattern. The leafy phase is associated with stem extension, while the leafless phase is typically when flowers (tiny yellowish cyathia) appear. Water more frequently from late spring through fall, especially when the plant is in leaf. In our mild winter rainfall climate, these plants enjoy regular winter water (in moderation) and mostly tolerate the rain (given good drainage).

    This species (like its toxic West African relatives) is tropical in origin and seems to be marginal where heat is lacking. Here where high temperatures are in the upper 60s and 70s for most of the summer, these plants rarely have much foliage and tend to grow very slowly.
