I have to agree with hcarlton. It is extremely vigorous in my collection's summery conditions and chokes out Drosera strikes and sprouts in a week or two. I also have it in a pot of U. bisquamata, and like bananaman has mentioned, you can hardly see the leafy stolens. I have to disagree with bananaman in that if I can't see the Utric very well then the sun "can't see it very well" either. I did have some in a larger venusta pot that I trimmed twice a month and it looked pretty cool, but the venusta didn't seem to appreciate it trying to grow up through the leaves and around the crown. An air-flow/gas exchange thing I guess.
