I had some indoor carniverous plants out in my pond last year, just an unnamed pitcher and unnamed sundew ( £1.99 ea from Morrissons I think). I potted them into clay alpine bowls and sat them in the shallows just a little proud of the water level and they had a great summer, plenty new growth & flowers. My pond is on partial shade & they seemed perfectly happy, right up until the first really hard frost when they were toast.
Will do something similar this year and see if I can catch them ahead of the cold.
Cheers
