This guide relys heavily on several books for identification of plants. In many cases, where there are many cross breeding species within a genus, we'll merely list the Genus and spp. as the species. Plants such as Lupines, and Sunflowers which have too many hybrids to list in any one place, will be placed in a general location. While we make every attempt to display correct data, mistakes are possible. Please let us know if you see any plant that is mislabled.
