Just a shot of some grafted Blossbeldia I did, two on Trichocereus and one on Hylocereus. They look much different from the seed grown plants Navajoa posted.
Will have plenty of seed if anyone wants some

ill take you up on those seeds

quite a clump! will you be degrafting one day? is that difficult?

I have no idea about degrafting this species, I was just going to leave them for the time being. Does anyone have any info on degrafting blossfeldia ?
