    An effective method of preventing cross contamination of utricularia species is to wrap each pot in a tall sleeve of clear, thin acetate plastic (available in craft/hobby stores). You would need to be growing the plants in round pots in order to make a good sleeve. The concept is much like the protective plastic sleeves that cut flowers and African Violets are sold in. The pots can be nestled up against each other without too much worry about seed fallng into other pots. I think an 8 inch sleeve should work wonders...provided you have a bright enough light source above.

    Just a thought

    philcula, that sounds like a cool idea. Except for the fact that I like U. subulata. Anywho, I just got back from a school trip, and noticed another U. subulata flower. I'll just have to hope for more. Oh, and thanks Dyflam!

    I find that my U. bisquamata never flowers indoors, and the U. subulata only produces claistogamous flowers.

    However, when I grow either species outside, they flower like crazy in spring, as it warms up; first, the U. subulata, then the U. bisquamata.

    I plan to try an experiment, placing a pot of each in the fridge for 6 weeks, and then returning to the grow chamber, to see if the temp change triggers flowering artificially.

    I've had both species flower for me inside and subulata did the cleistogamous thing outside. I'm more inclined, with my limited sample size, that this correlational, as opposed to causality.

    U. subulata is very pleiomorphic, your plant is not a special form it is just one of a million diffferent veriations on flower structure. I have seen differences in individual flowers on the "one" clone that has managed to take hold in my binata complex pots. Don;t be suprised if the flowers on your switch up to some "new" shape

    I have only once seen my U. bisquamata flower inside, and the U subulata never produced yellow flowers inside.

    Two years in a row, however, I see the U subulata produce scores of yellow flowers in Spring, and shortly afterwards, the U. bisquamata does the same... and then, as it gets hotter, the U. bisquamata stops flowering, and the U. subulata continues producing cleistogamous flowers.

    I'll run a controlled experiment, soon, though, and we'll see if temp changes induce flowering.
