Your favorite sources of information
Thanks to zenpotter and all the generous gardeners that attended the plant swap and gardening tea last weekend, I have developed a new obsession and need help researching perennials in order to support my new addiction.
What are your favorite sources of information on Zone 4a perennials? It seems like there are a million resources on the web but what are your favorites? Also what are the titles of "must have" reference books.
I would also like suggestions on how you catalog or keep track of the plants you have.
Thanks for your help. - a girl named max -
