Delaware Wildflowers

Guides
Two problems with field guides: they list some plants that don't grow here, and they don't list all the plants that do. (Claude Phillips' Wildflowers of Delaware and the Eastern Shore has been out of print for years, and doesn't reflect changes to Delaware's flora since the 1970's.) These guides are an attempt to remedy that. Only plants that are currently found wild in Delaware are listed. I've tried to give identifying features that are easily visible, and can be described in non-technical language. Photos showing distinguishing features are included, if I have them.

To use these guides to identify a plant, you first need to know its genus — the first part of its scientific name. So if your field guide tells you it's a fleabane, the guide to Erigeron will tell you which it is.

I've just started on these. The flora of Delaware includes about 800 genera and 200 families; only a few are available here, as listed below. I'd appreciate any comments; please e-mail me at
