A shrubby, semi-prostrate columnar cactus with tuberculate ribs.
It forms untidy, much branched bushes 1-2(-5) meters high.
This plant has an attractive grey white bloom on the new growth.
They are well adapted to their scorching summers, and take advantage of rain and warm weather with rapid growth any opportunity they can. All through warm weather, with the slightest hint of moisture, they’ll grow.
Cold nights and low daytime temperatures will put a pause on new growth, as will dry conditions.
