Native Plant Guides for Willamette Valley Species

Wildflowers of the Pacific Northwest (2006, reprinted 2014)

by Mark Turner and Phyllis Gustafson

Timber Press Field Guide

Very basic key with photos, limited number of plants covered. More up-to-date than other definitive guides.

Mountain Plants of the Pacific Northwest (1995)

by Taylor and Douglas

Not a definitive key to Identifying species. Covers ferns, conifers, hardwoods, shrubs, forbs, grasses.

Plants of the Pacific Northwest (1994, revised edition 2004)

by Pojar and Mackinnon

Useful features, and interesting notes about the plants covered, but not sufficient for definitively identifying species. Covers 800 species found from the coast to the western Cascades.

Flora of the Pacific Northwest (1973)

by Hitchcock and Cronquist

Classic, authoritative guide, key, and portable plant ID manual. Still widely used, but now outdated, as the nomenclature and distribution of genera have changed. Covers nothing south of Eugene.

Update in progress, see http://www.pnwherbaria.org/florapnw.php
