The plant 'bible' Flora is a 2-volume set nearly five years in the making, with contributions from over sixty writers lending to glossy photos and a reference which covers everything from weeds to the best plants for a garden. This isn't just a listing of plants alone - it covers the largest, best plants and offers color photos taking in pristine national parks around the world. A CD-ROM provides links to gardening web sites; but the meat of this reference lies in its extensive coverage of over 20,000 plants. A top pick.
