Welcome to Ceanothus ~ See, I Know This!

We are an association of professional, hobby, and student field botanists interested in educating each other to KEEP BOTANY ALIVE! Our desire is to create a supportive environment to learn botany identification skills from one another and to share our knowledge of plants and plant communities.

We meet regularly in the Sierra foothills, Sacramento, and (*new*) Chico, California, regions to practice keying out plants using The Jepson Manual and other plant identification resoures.

Our goals:
* To practice identifying plants;
* To use The Jepson Manual (and other identification resources) and become more familiar with plant terminology;
* To share our knowledge and educate each other about plant taxonomy;
* To discuss and learn about our California plant communities; and
* To have fun!


If you are interested in attending our regular plant identification workshops, please send an email to Ceanothusfieldbot [at] gmail [dot] com and we will respond quickly!
