Hi all,
I'm always looking for a new hardy cactus to try out in my garden, so far Opuntias (of course) and Escobaria missouriensis have done very well, but i would love to expand.

Here is what i already have, stuff big enough to trade cuttings of is marked with a *

Opuntia humifisa**
Opuntia NOID "trailing cactus" spineless (likely O. humifisa)*
Opuntia macrorhiza(?)*
Escobaria missouriensis
Opuntia polyacantha var. rhodantha 'Dark Knight'*
Cylindropuntia imbricata (didn't make it though last winter outdoors)*
Cylindropuntia leptocaulis (didn't make it though last winter outdoors)
Opuntia fragilis var dentada (would like a spiney var as well)

Delosperma "John Proffet"*
Delosperma "fire spinner"
Delosperma basuticum
