This species is remarkable for the thick white wool on the back of new leaves and on the tips of new shoots, as well as for its “bullate” (bumpy or pebbly) leaves and its beautifully contrasting red flowers. It has begun to be widely used in hybridization, and has even been crossed with micro-miniature species.
It hails from southern Brazil, and was collected on the island of Florianopolis. Its typical habitat is rocky steep cliffs, where it will trail tubers on “stolons” down the slope.
A second collection of the species has recently been made, further south in Brazil, and at higher altitude. This collection is named after the collection location, Canyon de Fortaleza, hence S. bullata Canyon de Fortaleza. In its natural habitat, it is subject to more sun and wind, and cooler temperatures. It apparently has a more compact form, without quite as much fuzzines as the collection from Florianopolis.
