I've also decided to include links to the California Native Plant Society and its various chapters so that people wishing to get involved directly in wildflower preservation and related activities can do so at the local level. I hope you will take advantage of the opportunities to learn more about our native plants through CNPS. I will add other noteworthy organizations as I hear of them. Thank you. -- Kahlee
Online Wildflower Identification Resources
The US Dept. of Agriculture has a Plants Database that can be very valuable for hunting down native plants.
The Berkeley-based CalFlora is perhaps one of the most popular databases for wildflower enthusiasts. You can search using a wide-range of criteria and narrow it down by county, plant community, elevation, etc. It has many professional photographer-contributed images of wildflowers that are reviewed for accuracy by CalFlora and are very helpful for identification.
Santa Monica Mountains NRA has a wonderful wildflower database online. Check it out at "Flower Finder" and other resources at Wildflowers of the Santa Monica Mountains National Recreation Area.
Wildflowers of Southern California is a very nice assemblage of photographs and detailed information on Southern California native plants and wildflowers prepared by Michael Charter.
For Northeastern states, Wildflower Identification, has a great qiuz tool to help deduce a particular species.
eNature's Wildflower Field Guide also helps identify flowers by shape, family, region, etc.
The Flickr group Wildflower Field Guide, North America is a living and breathing resource where you can see images of identified wildflowers. Also on Flickr, get help identifying wildflowers and all sorts of things as ID Please.
