The California Native Wildflower Poster features 150 native species as they bloom each month.   The poster features both prolific, common and rare species that are native specifically to the Central Coast / Bay Area.  Approximate radius of the listed species is centered on San Francisco, extending North through Marin County, South through Santa Cruz County and Diablo Mountain as the eastern border.  Many of these species are found up and down the length of the west coast.

Some species listed are rare, endangered, or poisonous.  For example the Tiburon Mariposa Lily, Calochortus tiburonensis, is a listed threatened species, endemic to California and only seen on one NE facing hill in Tiburon, California. We heavily relied on the Calflora database to produce the data on this poster.
