Kim,
Gorgeous Mamm. I don't know about this particular Mammillaria, but many Mamms bloom in the winter. I have several starting to bloom now. Just sit back and enjoy.

Hi Kim,

I love your collection! You have some beauties. Your Mammillaria plumosa-yep, that's it alright-is gorgeous. I just posted a pic of mine. Many Mamms do bloom in late winter.

This has been on my list of 'must haves'. What a beautiful plant.

Very nice little Mamm, I love those plumose radials on this species Kim. I have two small ones, no flowers yet so maybe mine will flower come winter time.
Thanks for sharing.

Cheers, CP
