Some leafstalks are marked by outgrowths at the base, usually on opposite sides. These were named stipules by Linnaeus, from the Latin word stipula, meaning “straw” or “stalk.” Not all plants have stipules, and among those that do, they vary greatly in appearance “and might appear as glands, scales, hairs, spines, or laminar (leaf-like) structures.” The remarkable, conspicuous stipules of Cunonia capensis, the African Red Alder, or Butterspoon or Butterknife Tree, are a focal point in the garden, almost always remarked upon by people who see them for the first time. The paired stipules are reddish in color and pressed together like cupped hands — or like butterspoons, I guess, whatever those are. (I say “butterknife” rather than “butterspoon.” I can see how the stipules are spoonlike, but I don’t apply my butter with a spoon, do you?)
An evergreen multistemmed perennial shrub or small tree from South Africa, this is one of my favorite specimen plants. I used to have several that I lost in our severe, years-long drought. The plant doesn’t need constant water, but it doesn’t like being dry, and I was careless (or all too responsible a California citizen). It also dislikes heat, and I’m now growing this one in a large container in part shade. While the tree can reach thirty feet in damp forests, it is seldom seen above fifteen feet in the open. Several sources report that it can be kept for many years in a container, and this has been my experience. It grows in zones 9–11 and prefers good drainage.
