    A Tour Through Our Iconic Flora

    California Native Plant Society presentation by botany professor and local author Matt Ritter

    May 3 (Thursday) 7:30-8:30 PM @ Vet’s Hall at Grand and Monterey, San Luis Obispo

    Join us for a book release celebration and visual tour of California’s iconic native flora

    There are more than 5,000 native species in California—one in five of which are now rare or endangered.
    Matt Ritter will take attendees on a visual tour through the state’s most iconic flora in a lecture based
    on his new book, California Plants. A richly photographed field guide to the state’s spectacular native
    plants, the book also seeks to raise awareness of the unique beauty that is at risk. Matt will use his beautiful photographs, insight, and humor to share the natural history of California’s fascinating plants. A book signing will follow the presentation.
