I started collecting a variety of Carnivorous plants last year; American Pitchers, Droseras,Nepenthes, Darlingtonias, and fly traps.

I have D'Amato, Slack, and Rice books on them, but often find they are lacking information I am looking for (i.e. size the pitchers or leaves will grow to).

Is there a book I am missing or is the information that I am seeking just scarce due to the number of varieties?

Thanks.
