Anyone know of a good online plant encyclopedia? I have been using the one on Martha Stewart's website, but I have found it very incomplete lately. Today, I picked up a Miniature Hollyhock, a Gaura, a Ligularia, and 2 Carpathian Harebells - none of which are on her site. Y'all know the 'complete' info that comes on plant tags. I have an info page printed up on almost every perennial in my garden and I keep them in a binder. Any suggestions are appreciated.
