Hi Jay,

        Had to put in my two cents worth on this :)!

        I've found that only certain Utrics (terrestrials) respond to high
water levels with flooding. My U.sandersonni and U.livida do fine with
lower water levels. You may say, yes, but your humidity levels are high,
well, I had these plants outside last summer in the open. Although the
humidity levels out on the West Coast are higher, last summer was
extremely dry. Anyways, they all stayed in flower. The only thing that
slowed them down were aphids (they love the flower stalks).

        However, certain plants like U.subulata seem to refuse to put out
flowers without the occasional flood.

        Not in my case, it seems to be the media. As someone in private
correspondance noted, his U.calcyfida plants were much larger when grown
in a looser media. I've unpotted plants from sphagnum and from peat/sand
mix, and the ones in the sphagnum always have a more extensive 'root'

        I agree. I've done this before and shocked Utrics which usually
flower non-stop. And they certainly do sulk. It took almost half a year
for one pot of U.livida to recover.
