I don't have any recent pics, but here's one of the first flower I got on my bladderwort. This one was a couple weeks ago.
Just sitting in a neglected tray of plant clippings/culls and snails.
If I get a chance, I may try and take a pic sometime this week, I've got probably a couple dozen flowerstalks, and about a half dozen flowers at any given time.
All I really see above water is the flowerstalk/flower.
