Mammillaria schiedeana

Hello,
I have a rebutia perplexa with a few tiny flower buds and I want to try and get some seed, Is rebutia perplexa self fertile?
Many thanks.

Hello,
unless the species is red in colour this may be a sign that the seedling is receiving slightly too much light, just move it out of very bright light, soon they should return green. Good luck!

Sorry here are some more patterns i took from my collection.

My mammillaria schiedeana is in bud!
