(Plant Identification for everyone)                                                   Introduction  |  Contributors      

How it all started -
From 2011 to 2014, I collected photos and wrote illustrated plant lists for Marin County, where I live.  I wanted to make it easy for you to find a plant, given a specific location or topic, by

·       Limiting the size of the list you had to choose from, and

·       Offering lots of photos to help you choose your plant.

·       Attaching captions to photos to add meaning.


This worked well, but it took too much work to put together each illustrated list. 


Since 2014, I’ve  been working on a database approach that will allow hundreds of photographers and authors to submit photographs and put together illustrated plant lists, to cover all of California.


To the right are the original articles, which you’ll find very useful if you happen to live in Marin County.
