The last VFT I bought was from Colosanti, and it looked quite different from what's in those pictures. Its leaves were much shorter and broader, and the trap's "teeth" were relatively long. I'd noticed them in the grocery store, and hadn't really intended to buy more; the three I had were enough for my purposes at the time. But on a later trip to that store, there was just the one left, and its substrate was quite dry and the plant nearly dead. I found the produce manager and explained that the VFTs needed to be kept well-watered with pure water. She let me buy it for half price. I didn't repot it, but I ran lots and lots of pure water through its substrate. It perked up a bit, but started dying slowly, putting out smaller and smaller leaves as the older ones died off. I rather expected it to not make it through the winter in the fridge, but when I repotted it in the spring, it took off better than the other three.
