Plant Research

Cornell University has the right idea. There is a massive plant list available there to browse before you grow some several thousand varieties. And it is user rated, not just University rated. Named simply Vegetable Varieties for Gardeners, it has mostly commercially grown items with a few heirlooms thrown in. I've been browsing it for the past couple of hours and have learned things about several varieties that I'd intended to grow. It isn't terribly complex, but is packed with good information.
