The AS-CO ( A. coahuilense x A. asteriasF1
hybrid ) Shows intermediate density of
hairy scales, while the number of
ribs vary from 5 to 8 (usually 5 like in the mother).
Relatively easy to grow. It is sometime seen as a grafted plant but
grows very well on its own roots too. Use mineral well permeable
substratum with little organic matter (peat, humus). Water
sparingly from March till October and keep
perfectly dry in winter at temperatures from 5 to 15 degrees
centigrade. (but it is Hardy to -7°C for short
periods) In the rest period no high atmospheric humidity!!
Sun Exposure: Light shade to full sun.
Propagation: They can be propagated easily from seed or graft.
