Cold Climate Cactus

We have had rain every day in the month of June and July is still bring plenty of rain too. Some seedlings have died under these conditions and others are growing like mad. There are probably some species relationship to the ones that survive these conditions and by the end of this summer I imagine I'll know which ones these are. The cold climate varieties in the Echinocereus, Escobaria and Pediocactus generics are all holding up very well and growing.
