Sue - This is the first year I have noticed them because of the small blooms. I was excited at first to see the fans because I thought they were my daylily fans showing very good rust resistance!
I never noticed them before that though. I am sure they came with the fill dirt and got big enough this year to actually send up scapes and bloom. I think the bulb to the left is a division from the first one. Perhaps a split into 2 bulbs but still attached to each other. Only one though sent up the scape and produced leaves. I was seeing the fans on them since Spring and was pulling them out since March until now. I am sure there are more out there that I can't determine yet to remove them.
Quite the mystery as to what this plant is!
