I was at a local lake in Mason county Wa. the first part of june, to check up on the local D.rotundifolia. When i noticed blooming U. inflata all along the shoreline. A couple months later i went back to take photos and could not find a one? My Q. is do they sink after going to seed? The lake was closed to the public due to budget problems. So very few people ever hiked past the locked gate.  |

Ah, I know that population of U. inflata. I used to live in Olympia; didn't they try to eliminate that population a couple years ago? Utricularia inflata is an invasive weed in Washington state. I believe after flowering, the floating appendages that held the flower aloft disappear and the plant goes back to its vegetative state. You wouldn't necessarily notice it from the surface unless you dig through the water and find the stolons.

Thanks for the info kitkor, will go back next late spring. One populated lake nearby the people pay the kids to go out and round up all they can find. Still comes back! The lake i go to, you have to hike over a mile to get to since they gated the entry. Thats a good thing, because there is a small population of large D.rotundifolia i was concerned about getting wiped out by the public.
