There's actually 3 species of cabomba that will flower, but I'm not sure exactly which one I have. I have a really great book that I use for reference, but I've loaned it to a friend temporarily. I'll post the exact species when I get my book back. Anubias flowers? I have some anubias nana. Does that species flower? I've got two pretty healthy nana plants, but never noticed a bud. Of course, it's just now getting to the healthy stage. It's had some problems in the not too distant past.
