Conservation status: Listed in
CITES appendix 2.
This crested cultivar is astonishing. It is derived from a large Mexican
cactus but the cultivar is compact, small, and presents a silhouette
made of heavily convoluted folds. The short living grey/green foliage is
arranged only at the top of the stem. The spiny grey stem will soon form
a fan-shaped or snaky ridged bush reminding of a boa asleep. Even if his
form is rare, this cactus is however resistant and easy to grow in an
acid draining soil, needs full sun.
