We have at least three different native species, but none of them are <"very common">, and they are all pretty inconspicuous unless they are flowering (and often they don't flower). Utricularia minor is probably the most "flowery one", and reasonably common in Scottish peat bogs etc.Utricularia is actually a native plant in the UK. Never managed to spot any as yet though!
OK if your house isn't too warm, but really difficult if you efficient central heating.Hard work on a window sill!
I managed suprisingly well with sundews. Only one I didn't get on with was S.Aliciae. I suspect the lack of sun was a factor. It was the least interesting of all sundews anyway
I think that in the winter they all need as much sun as possible, but fairly cool.I suspect the lack of sun was a factor.
No, they seem to get by without any feeding. <"Utricularia gibba"> has really small bladders, so it maybe trapping very small food items (Rotifers?).Do you feed yours with waterfleas or similar?
