Did you know that Southern California is host and home to nearly a thousand species of woody perennials (aka trees)?

Magnolia x soulangeana. Liquidambar styraciflua. Platanus racemosa. Tabebuia impetiginosa.

Translation: Tulip Tree, American Sweet Gum, Western Sycamore, and Pink Trumpet Tree.

According to Don Hodel, author of Exceptional Trees of Los Angeles County, we live in “one of the most diverse urban forests in the USA.”

Jerrold_TurneyFor three Saturdays, The Arboretum presents, “What Tree Is That?,” led by Dr. Jerrold Turney, curator of the camellia gardens at the Huntington Library and Botanic Gardens, research horticulturist at the L.A. County Arboretum, and plant pathologist for the Department of Agricultural Commission/Weights and Measures for the County of Los Angeles.

Beginning on Saturday, September 7th, each lecture will cover 15+ tree species, followed by a walk in the Arboretum to see and identify the actual trees that were covered during the lecture. Dr. Turney will teach you how to identify the trees and talk about their growth habits, their native countries, how they should be cared for, any common diseases or insect pests that attack them, and the best place in your garden to plant them.

Make sure to bring water and a hat, and wear your walking shoes!

Conveniently, the class ends at noon, just in time to ease your walking legs for a bit of nosh at the Arboretum’s Peakcock Café. Afterwards, you may be drawn to explore the greenhouses and the Garden for All Seasons to see all the flourishing veggies and bond with the chickens.
