Stem: Solitary or clustering,
Ribs: ca. 14.

Cultivation and Propagation: This species loves a very permeable, coarse mineral soil as well as to be strictly kept dry throughout the winter quiescent period since it is very sensitive to any moisture excesses, To prevent rottenness it is also advisable to surround its root neck by very rough sand or grit, this help a fast water drainage and an appropriate air circulation. Plants are quite frost hardy -5 (-10)° C.
Watering Needs: Water moderately in the growing season, keep dry during the winter rest
Frost Tolerance: Overwinter in a cool place (at 0/10°C) this is important for the flowers as well as for plants health. Without this cool winter period they normally wont get any buds.
Sun Exposure: Needs a full sun exposure (light shadow my be useful in the hottest summer days)
Propagation: Seed, cutting, grafting.
