Not that I know of. If your mihanovichii is a moon cactus, I wouldn't count on it bringing a fruit all the way to maturity, though.

Someone in this thread from twelve years ago seems to have done it, but all the images are dead. I don't think there's much restriction on interspecific breeding within the Gymno genus, if at all, so I'd say go for it. https://www.shaman-australis.com/forum/index.php?/topic/32541-gymnocalycium-threa...

I am obsessed with Myrtillocalycium chimaeras. Don't know why; it's probably my inner mad scientist. To that end, I'm looking to purposely create one using a grafting technique that has never before been documented, probably for good reason. Without further ado, I give you Project Frankenspine , in ...

Bad news. None of the seeds germinated, and the project is dead until the next flowering season. See you next fall!

Well, this is just a bit disappointing. I noticed the fruit was starting to shrivel today. I lightly tapped it and it fell clean off. In an effort to see what was the matter, I opened it up and got this: https://i.imgur.com/j3Jd5QM.jpg Is there any conceivable hope of getting a viable seed from this...

I'd say that's green enough to survive on its own, but in my experience degrafting these guys is very hit-or-miss. In my case, just miss. Don't do it without rooting hormone.

I've got news, and some of it's good. First, what I thought were amerhauseri are probably just baldianum. Second, I was only able to create one successful cross. Hibotan and Baldy #1 both aborted their flowers. Baldy #2 I accidentally spayed while trying to pollinate, but it's a moot point because i...

Okay, new plan. I went back and bought a second amerhauseri plus its two babies. I crossed the two mihanovichii together, then put what was left of the pollen in the fridge. https://i.imgur.com/uRnAVce.jpg Anyway, it just occurred to me that I don't know if mihanovichii can even hybridize with amerh...

Hi everyone! I'm new to the world of cacti, but I've been working fast. Recently at Walmart I came across a grafted moon cactus that was flowering. One thing led to another, and now I have three store-bought gymnos, all in various stages of flower growth. https://i.imgur.com/JJeXzMX.jpg Seen above a...
