What Kind Of Peanut Cactus Is This?

Question

Recent acquisition of a small plant (labeled Chamaecereus silvestrii). Green, writhing stems looking exactly like the classic peanut cactus. BUT, the first flower on the end of one stem is white! This seems at odds with all pictures I can find. What might it be?

Answer 1

I found that Chamaecereus silvestrii is a synonym for Echinopsis chamaecereus, which is the peanut cactus. There are many different cultivars with flower color such as violet, yellow, purple, and violet-red besides the traditional orange-red.

I did find a similar cactus Echinopsis 'Westfield Alba', a hybrid with daisy-like white flowers, which could be what you have. (There was no photo attached.) Here is more on its care:
