Reference List for Oregon Wildflower Identification

Site Description
The Native Plant Society of OregonThe NPSO local chapters "hold meetings, field trips, and plant shows and sales for members and non-members alike, making available the knowledge and wonder of our native plants to everyone."
Oregon Flora Image Project Excellent identification photographs of the flora of Oregon, by Dr. Gerald (Gerry) Carr, who is associated with the Department of Botany and Plant Pathology at Oregon State University. You'll need to know the scientific name of the plant you seek.
Common Plants of the Upper Klamath Basin This is a large PDF file of a 272 page book put together apparently by Rabe Consulting and the Klamath Basin Chapter of the Oregon Native Plant Society. It provides excellent of Ferns and Horsetails; Conifers; Flowers; Hardwood Trees and Shrubs; Grasses and Grass-like Plants; and Lichens, Bryophytes, and Blue-green Algae of the 7,230 square mile Upper Klamath Basin in southern Oregon and northern California. This includes the famous Crater Lake National Park.

The book includes a photograph and description of by my estimate nearly 500 plant species.
Mountain Plants of the Western CascadesTanya Harvey is a self-proclaimed amateur botanist and gardener who is also an artist. She has combined those skills well in this website, which she is using as a repository and expository of the work she has done botanizing in the Western Cascades of Oregon while she prepares a book on the same for publication.

There are plant lists for various locations in the Western Cascades. These can be helpful in identification by knowing what plants can be found at these spots. The "Plants and Places" blog also provides excellent information and photos on the plants of the Western Cascades.
Reny's WildflowersReny Parker's wildflower galleries, with "over 1,820 images identified to 79 plant families." Includes family and species common and scientific names, photo location. Searchable by color, shape, location, and name. Very nice photographs.
Turner Photographics Wildflowers of the Pacific NorthwestOver 7,000 excellent photographs from Washington and Oregon and northern California, by one of the co-authors of 'Wildflowers of the Pacific Northwest' (see below.) These are indexed by Latin and Common name, by blossom color, and by blossom characteristic. Good information about each species, and the detail page includes a county-level map of distribution.
Wildflowers WestMark Lee Dixon's & Darice Susan Dixon's wildflower website, with wildflowers organized by blossom color. They usually include multiple photographs of a plant, with at least one of the blossom and another of the whole plant or the leaf infrastructure to help with identification. Additional informative text is included, including common and scientific names. Very nice photographs.
Wildflower Field Guide - DesertUSAOver 50 species of wildflowers found in USA deserts, organized by flower color. Common name, scientific name, and desert regions in which they are found - Mojave, Sonoran, Chihuahuan, and Great Basin. These deserts touch 7 states in the western US.
Lady Bird Johnson Wildflower Center at the University of Texas at AustinPremier native wildflower information site in the United States. "Native Plant Database - Search 7,024 native plant records by traits or names. Image Gallery - Browse through our collection of 23,770 native plant images. Ask Mr. Smarty Plants - Have a question? Mr. Smarty Plants has 3,584 answers. How To Articles - Don't know where to start, try one of our articles."
USDA Plants DatabaseGreat resource! Their own description: "The PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories." Provides these important (to me) pieces of info: 1) Listing by state and county within a state where specific species have been identified. 2) Scientific name synonyms are listed. 3) Scientific names are matched to a widely-used common name. 4) Photographs of many species. 5) State by state list of all the species identified in that state. Official Citation: USDA, NRCS. 2009. The PLANTS Database (http://plants.usda.gov, 22 June 2009). National Plant Data Center, Baton Rouge, LA 70874-4490 USA.
Flicker Wildflower Field Guide, North AmericaOver 9,000 Flickr member photos tagged with wfgna. The WFGNA group has good tagging requirements for their excellent photos, so you'll find, in addtion to the photo, the state in which the photo was taken, and at least a common name and the scientific name as identified by the contributor. After you get to the linked page you should add search criteria, including the state name, the color of the plant, or scientific name, to reduce the number of photos. Several states have several hundred photos(California has over 1,500!) so you'll probably want to add color to the search criteria.
Book at Amazon: "Featuring more than 1240 stunning color photographs, this comprehensive field guide will remain a trusted, authoritative trailside reference for years to come. It describes and illustrates 1220 commonly encountered species" - This book appears to be the regional guide one needs for wildflower identification in the Pacific Northwest. It has received excellent reviews on Amazon.
Wildflower Information.orgFrom the site: "WildflowerInformation.org is a resource for wildflower enthusiasts and gardeners. With a growing interest in the environment and natural gardening, our objective is to offer comprehensive information that is easy to use, and accessible for those from the casually interested to the expert."

While this information doesn't appear to be on the website itself, WildflowerInformation.org seems to be owned by American Meadows, the "recommended wildflowers seed supplier" of WildflowerInformation.org.
Book at Amazon: National Audubon Society Field Guide to North American Wildflowers: Western Region Covering the region from Alaska to California and east to the Great Plains, this well-produced, compact guidebook contains more than 940 photos of over 650 species of wildflowers of western North America. The color images are grouped by flower color to suit the needs of inexperienced enthusiasts. I think anyone interested in wildflowers in the western United States should have a copy of this guide. Situated in the Eastern U.S., I use the Eastern Region guide extensively.
