    Dr. Phil Bergman

    Interesting and Rare Palm Trees That Can Be Grown in Southern California

    Our speaker is Dr. Phil Bergman, well-known author and speaker on palm trees and cycads in Southern California, and owner of Jungle Music Nursery in Encinitas, where he has been actively propagating and growing many types of rare tropical plants for the past 38 years.

    In Southern California you often see the same palms over and over again such as the Queen Palm, Mexican Fan Palm and Pygmy Date Palm, but there are scores of other beautiful palm trees that thrive in our area and add diversity and beauty to the garden.  With this presentation you will learn about over 75 beautiful and rare species that you can easily grow, including some newly introduced species of Dypsis, Ravenea, Roystonea and Hyophorbe.  The presentation will cover cultural requirements, mature sizes, special needs and any hidden “secrets” to successful growth.

    Dr. Bergman began Jungle Music Nursery in 1977 where he grows over 1000 species of tropical plants, with a quarter million plants for sale, on the 3-acre site in Encinitas. The main specialty has been palm trees, and the nursery is known country-wide for being a source for rare plant material. His website,, was one of the first palm tree websites in the world. It contains over sixty articles that he authored on the cultivation and care of palms and cycads and more than 5000 plant photographs, including both habitat pictures and domestic plantings. Dr. Bergman holds a biology degree from Stanford University and a medical degree from UC San Francisco Medical School and has been a practicing emergency physician with Scripps Hospitals for 38 years.  He is past President of both the Southern California and International Palm Societies.

    UC Berkeley Bee Lab

    California Bees & Blooms

    California is home to over sixteen hundred species of undomesticated bees—most of them native—that populate and pollinate our gardens, fields, and urban green spaces. In this absorbing guidebook, some of the state’s preeminent bee and botany experts introduce us to this diverse population. California Bees and Blooms holds a magnifying glass up to the twenty-two most common genera (and six species of cuckoo bees), describing each one’s distinctive behaviors, social structures, flight season, preferred flowers, and enemies. Enhancing these descriptions are photographs of bees so finely detailed they capture pollen scattered across gauzy wings and iridescent exoskeletons. 

    Drawing from years of research at the UC Berkeley Urban Bee Lab, California Bees and Blooms presents an authoritative look at these creatures, emphasizing their vital relationship with flowers. In addition to opening our eyes to the beautiful array of wild bees in our midst, this book provides information on fifty-three bee-friendly plants and how to grow them. Just a few square feet of poppies, sage, and phacelia are enough to sustain a healthy population of wild bees, transforming an urban or suburban garden into a world that hums and buzzes with life.
