They're gorgeous! Congratulations on getting them to bloom - if I'm not mistaken they only bloom once a year so it's a long wait, but from your results, well worth it.

Since I live in a colder zone I can only grow them in pots and believe me, it's not easy to get them to bloom. After years of trying with only a few successes, I finally gave up. Last year I threw all my cactus plants away - some were over 30 years old and grown from seed.
Your pictures are a reminder that cactus blooms are indeed some of the most strikingly beautiful flowers around.
Thanks for posting.

Thanks
The ironic part of this is,they actually need 'some' cold temps to bloom.
