There's nothing so annoying as the straight species Utricularia bisquamata. It seeds itself everywhere if the seed pods are left on and will contaminate a Utricularia collection in double quick time. It usually turns up as a hitchhiker, not just from amateur collections either. Having said that it's not an unattractive flower, even if it is small. I try to control it by dead heading, that keeps it within the confines of its own pot.
A far more attractive plant is Stephen Morley's cultivar Utricularia bisquamata 'Betty's Bay'. It has much larger flowers and in my experience doesn't seed itself around. This is one of MrsG's favourites
There are other forms, of which I have some specimens, that are variously described and we will see how they progress in the Solar air pump test.
I gathered together all the invasive form of U. bisquamata I could find and lumped it together in a deep 10" saucer. It sits outside, well away from any other carnivorous plant, with no protection. It's evidently still enjoying itself in December.
Nice pictures Fred, these may be one of the most common and invasive Utricularia but the sheer exuberance of the flowers never fails to make me smile. Mine too have been flowering for a long time this season.
My first inflorescences of the year of what I think is ‘Betty’s Bay’ Due to my habit of mixing old peat with new potting material these are popping up all over the place, although I don’t remember throwing any supposedly dead plants away.

A bit of a blessing that 'Betty's Bay' popped up, rather than it''s rowdier sibling, the regular and much weedier U. bisquamata.
And thank goodness it wasn't the ubiquitous, cleistogamous subulata, that infects so many CP pots, usually as a hitchhiker or stowaway, and is generally not very welcome, upon its eventual discovery...
...it's kinda like what used to be called a "social disease", but for CPs.
