There has been a few topics about this butterwort lately. I have had pretty good success with these conditions. I purchased this at Lowe's quite some time ago, and the thing was looking pretty bad. I transplanted it from it's little cube it was in into a 5" pot with about 70% LFS and 30% pummice. It recieves about 4 to 5 hours of direct sunlight in the morning with bright indirect light the rest of the day. The humidity is around 60 to 70% and it sits in about 1cm of water. It has doubled in size and produced 3 flowers this spring as well as numerous plantlets.
