Gasteria species all come from South Africa, with a couple of species whose ranges spill over into adjacent Swaziland (in the east) and southern Namibia (in the west). Among those found only in South Africa is Gasteria bicolor, from the south-central part of the country, in the general vicinity of Port Elizabeth.
Gasteria bicolor is primarily a spring-flowering species, though it may begin in the latter part of the winter. The flower stalk may lack branches, but typically it has a few, and robust plants may have up to eight. The dangling pot-bellied flowers arrayed along the flowering stems resemble those of other species in the genus, but are on the short side at ½ to ¾ of an inch (12 to 20 mm). They are light pink at the swollen base, fading to white in the middle and with green striping toward the tip.
