fail?

A picture of one of my plant failures.

I don't know why, but I always seem to do badly by carnivorous plants. And I think they're so cool. My Sundew died. This Venus Flytrap is just hanging in there. Look at all the nasty white gunk. Either it got too much moisture (is that possible with these plants?) or I forgot to give it distilled water a few times and the salts built up.... It does have a little bit of new growth in the center, so maybe if I'm more diligent it will recover...
