On a whim, I took a moss congested pot of D. dichotoma, plunked the mass out of the pot, and set in in the water of my bog about 2 weeks ago. When I checked it today, I am astounded at the growth it has put out. It is reproducing at least 3 times as rapidly as in a terresterial medium, and the growth is thick! At the current rate it will double its biomass in a month, possibly due to increased available prey.
I am about to try the same thing with U. pubescens, and will continue with other species if I have the success I expect. Preliminary data suggests that these plants do not like pots!
