BAGSC members were treated to an inspirational garden tour of Cordelia’s sustainable, drought-tolerant, and enchanting garden and home before the BAGSC Quarterly Meeting on June 4, 2016. Stay tuned to the blog for an article by Cordelia about the garden, its inspiration, planning, and building and more photos.

In the meantime, as promised, Cordelia has provided us with her plant list. All of the plants listed below are available from Australian Plants Nursery in Ojai, California.

The Arboretum is bringing back botany Professor Matt Ritter for a lecture and walk, discussing and celebrating the Arboretum’s Australian trees, “Australian Trees for a Drought-Stressed Southern California”.

Saturday, March 19, 2016, 10:00 am – 12:00 pm

Los Angeles Arboretum
301 N. Baldwin Ave, Arcadia, CA 91007
10 am – 12 noon / Bamboo Room
Matt Ritter, Instructor

$30 members; $40 per non-member (includes Arboretum admission)
Reservations are preferred: Please call 626.821.4623 or pay at the door

Whether it’s an El Niño year or not, it’s dry in California and likely to get dryer. Trees from Australia can be part of the solution toward creating beautiful, diverse, and resilient urban forests that use less water.

We’ll explore drought-tolerant, appropriate Australian species for planting in our Southern California environment. This event will be partial classroom lecture and discussion, and part tree walk in the Arboretum’s world class collection of Australian trees. Come learn about Acacias, Eucalypts, Callistemons, Melaleucas, and Brachychitons, and so many more great Australian trees.

Matt Ritter is a professor in the Biology Department at Cal Poly, San Luis Obispo. He has authored numerous scientific papers and botanical treatments, including the second edition of the Jepson Manual, the Flora of North America Project, and a natural history guide to San Luis Obispo’s native plants. He is also the author of A Californian’s Guide to the Trees Among Us, the state’s most popular natural history guide to the urban forest.
 
He is the California Coordinator of the American Forests Big Tree Registry, holds a Kenan Fellowship at the National Tropical Botanical Gardens, is the chair of the City of San Luis Obispo Tree Committee, and editor-in-chief of Madroño, the journal of the California Botanical Society. He is an avid woodworker and gardener.

Many BAGSC members have been asking about where they can find information about drought-tolerant plants. You can find a lot of information about drought tolerant plants on the web. Here is a section from the Wikipedia entry I was directed to after googling “lemonade berry”:

Rhus integrifolia, the Lemonade Berry’s leaves are simple (unusual in a genus where most species are trifoliate), alternating, evergreen and leathery, ranging from two to four centimeters wide on reddish twigs; length of leaves is five to seven centimeters. Leaves are toothed with a waxy appearance above and a paler tone below. The flowers which appear from February to May are small, clustered closely together, and may be either bisexual or pistillate.[1]

These fragrant flowers exhibit radial symmetry with five green sepals, five white to rosy-pink petals, and five stamens. The small flowers are only six millimeters across. The ovary is superior and usually has a single ovule; although in pistillate flowers, the stamens are small and infertile. The mature fruit of Rhus integrifolia is sticky, reddish, covered with hairs, and about seven to ten millimeters in diameter. The elliptical fruit presents tight clusters at the very ends of twigs.

Young plants manifest smooth reddish bark, while more mature individuals have cracked, even scaly, grayish bark with the smooth red bark displayed underneath. Twigs are rather stout and flexible, and reddish bud ends are diminutive and pointed. There is often a multi-furcate branching structure from the base of the plant. A mature plant is large and thicket-like with a sprawling arrangement.

Notice how many painting cues for color and structure are in that entry! It also tells me when it flowers.  Very useful and free information! Next, if I hit “images” for lemonade berry – bingo – what a selection!

The following is a list of California Native plants and their drought-tolerant adaptive strategies, compiled for us by Jennifer Funk, Assistant Professor of Biological Sciences, School of Earth and Environmental Sciences, Schmid College of Science and Technology. Please keep in mind that the exhibition is open to any drought-tolerant plants from around the world, not just California natives! This list was handed out at a BAGSC Quarterly meeting earlier this year. Future articles on the blog will list characteristics of drought-tolerant plants.

Let us know your questions, or any future articles you would like to see on the blog about drought-tolerant plants.

A few drought-tolerant species, all native to southern California:
Scientific name, Common name

Drought deciduous (plants that drop their leaves during dry season or periods of dryness)

Calliandra eriophylla, Pink Fairy Duster
Encelia californica, California Bush Sunflower
Encelia farinosa, Brittlebush
Keckellia antirhhinum, Yellow Bush Penstemon
Ribes aureum, Golden currant

Small leaves (small leaves have a reduced surface area, and so lose less water)
Adenostoma fasciculatum, Chamise
Arctostaphylos species, Manzanita
Artemisia californica, California sagebush
Ceanothus species, Ceanothus
Cercocarpus minutiflorus, San Diego Mountain Mahogany
Epilobium canum, California Fuchsia

Isocoma menziesii, Coastal Goldenbush
Isomeris arborea, Bladderpod
Lotus scoparius, Deer Weed
Lycium californicum, Coastal Boxthorn
Mimulus aurantiacus, Bush Monkeyflower
Prunus ilicifolia, Hollyleaf Cherry

Deep taproot (taproots find water sources deep below the soil surface, and are often thick and fleshy, so they can store available water)
Pinus species, Pine
Platanus racemosa, California Sycamore
Populus fremontii, Western Cottonwood
Quercus agrifolia, Coast live oak

Succulent leaves (succulent plants store water in their fleshy leaves, stems and roots)
Agave species, Agave

Dudleya species, Dudleya
Opuntia species, Prickly pear cactus
Yucca schidigera, Mohave Yucca

Asclepias californica, California Milkweed
Encelia farinosa, Brittlebush
Galvezia speciosa, Island Bush Snapdragon
Malacothamnus fasciculatus, Chaparral Mallow, Bush Mallow
Salvia apiana, White sage

Evergreen, sclerophylous leaves (evergreen leaves stay on the plant year-round; sclerophylous leaves have a hard surface and are frequently closely spaced together)
Arbutus menziesii, Madrone
Baccharis pilularis, Coyote brush
Eriodictyon crassifolium, Thick-laved yerba santa
Heteromeles arbutifolia, Toyon
Malosma laurina, Laurel sumac
