This pic is of a big boy that looks a bit like a lophophora underneath the flower, and here's one of an amazing grafted ball of fun I got last year (rootstock is slightly sun bleached, but quite healthy otherwise):
Looking forward to more and bigger flowers soon!
Edit: one of my gymno triplets also started to bloom some time between 3 hours ago and now! I was hoping all flowers would open up together, but it's still pretty :)
Ugh, I love cactus flowers!! They’re so pretty and huge considering the tiny and/or nondescript cacti they usually come out of.
(Not sure how to link/upload images on mobile otherwise I’d post a few pics of some gorgeous ones I saw at Huntington gardens a few weeks ago)
