Wow, I'm glad I found this forum! I was given 6 cactus pups 6 years ago, each was labeled w/ the proper names but sadly they washed away. From the flower colors and the distance of the cactus thorns I think I have 2 varieties(?). I have now over 60 plants and 180 pups rooting and would like to sell these with proper names. Any info is very much appreciated.
I'm adding that 2 years ago I had one flower bloom, last year over 200 flowers. The man who gave them to me was a hybridizer.
