Clivia caulescens is apparently lithophytic at God's Window, South Africa, and I saw at least a couple growing up in trees in open forest in Limpopo Province near Woodbush mountain. The caulescens plants at God's Window probably started off life in the ground, but the stalks flop over when they get long and sprawl over the bare rocks. The "Swamp Clivia" is C. robusta. I've not seen it growing wild in habitat.
