VFTs planted in undrained tray and kept under water (Dec03/Jan04):
The same tray Jul04 ready for dormant rest in refrigerator:
Once I was transplanting several dozens of VFTs and I decided to put the trimmings and broken pieces into this tray and see if they would sprout and then to grow them as semi-aquatics. It has been more than 4 years now and they continue to thrive. I have only once cleaned out the tray, removing about 30 plants and refreshing the 100% peat moss media with new peat moss. The Sphagnum and other moss are strictly volunteers.
The earlier photo shows the plants in vigorous growth after recently being removed from their dormancy in the refrigerator where their tray was completely filled with water covering them and then the lid was snapped on.
The later, more recent photo shows them to be slowing down and I shall shortly return them to the refrigerator for another dormant period.
I grow many other VFTs in more normal ways, but I just wanted to prove to myself that they were even more flexible and durable than we generally give them credit for.
