Published  in: Frank G., Kakt. und and. Sukk., 20 (12): 238 - 239 (1969)

cv. "Yellow spines"

Origin Garden origin (Nursery produced cultivar)

Conservation status: Listed in CITES appendix 2.


A plant with an elonged apical meristem line (Cresting?)
 

 




Cultivation: Very difficult to find high quality plants of this species in cultivation, S. rauschii 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.
For its sensitive roots this species is frequently grafted to avoid root problems. Plants grafted on Opuntia compressa are easy to grow and quite frost hardy -5 (-10) C
Water moderately in the growing season, keep dry during  the winter rest.
Overwinter this plant  in a cool place (at 0/10C)  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
