By Bart O’Brien, Garden Director

It’s that time of year again! The Regional Parks Botanic Garden’s Spring Plant Sale will be held on Saturday, April 15, 2017, from 10:00 a.m. to 3:00 p.m. Friends members-only sale is held from 9:00 a.m. to 10:00 a.m. Friends memberships may be purchased at the garden on the morning of the sale starting at 8:30 a.m. Many volunteers and garden staff members will be on hand to help you find the right plant for your garden and to provide answers to your questions. For a full list of all of the plants that are in the sale (by scientific name, quantity, and pot size), visit the Friends website: We continue to update the plant list, often until the afternoon before the sale, as we add new things and delete plants that aren't quite ready for sale—so do visit the website more than once! 

Early shoppers DO get the best selection, and some plants may sell out quickly. 
Here are a few highlights from the sale:
Poppies! From the stately Matilija poppy (Romneya coulteri) to both island and mainland species of bush poppies (Dendromecon harfordii and D. rigida) to the perennial coastal form of California poppy (Eschscholzia californica var. maritima), we’ll have all of these spectacular and justly famous California natives in quantity.

Trilliums! We are very pleased to be able to again offer mature seed-grown California trillium species. Our volunteer plant propagators have been tending these plants for years. (All have been grown from seed here at the Botanic Garden and are a minimum of six years old; many are multi-stemmed, and all are mature, blooming-sized plants.) In line with their age and the time our volunteers have invested in growing them, these plants are priced accordingly. The following kinds are in the sale this spring:

  • Trillium albidum – white flowers, green leaves mottled with red-brown and dark green.
  • Trillium angustipetalum – richest dark red flowers, green leaves mottled with red-brown and dark green. Sepals, on our plants, are dark red and lie flat.
  • Trillium chloropetalum – white, red, and pinkish flowered forms; all have green leaves mottled with red-brown and dark green.

Milkweeds! For monarch butterflies! We expect to have two species (as long as they have emerged from their winter dormancy) that are especially attractive food plants for our local monarch caterpillars: Narrow-leaved milkweed (Asclepias fascicularis) is the hands-down favorite with caterpillars, but showy milkweed (Asclepias speciosa) is usually considered the more beautiful garden plant.

Ferns! We’ve been growing many of California’s ferns from spores over the past two years, and we will have a few small plants of several very rarely sold species. (They are rarely available because few have the patience and/or the favorable conditions to grow these highly desirable plants.) Kiamara Ludwig, one of our two Interpretive Student Aides, has a special interest and expertise in growing these plants, and we are pleased to be able to offer some of the first of her spore-grown species propagated here at the Botanic Garden:

  • Silverback fern (Pentagramma triangularis ssp. viscosa) – Looks and performs just like our common goldback fern, but this one is strikingly white on the underside of each frond. This diminutive species is most at home growing in a shaded wall, rock crevice, or container. Usually grows best with additional summer water, though established plants can go completely summer dormant. Vigorous plants in 4” pots.
  • Northern maidenhair fern (Adiantum aleuticum) – Always a favorite with garden visitors, this species has shiny jet-black stems and lush apple-green foliage. Excellent in both containers and a shaded to partially sunny garden. Plants will not tolerate drought conditions in most gardens in our region. Easily grown in our immediate area and near the San Francisco Bay, this plant can be difficult to keep happy in hot inland gardens. Vigorous young plants in 4” pots.
  • Sonoran maiden fern (Thelypteris puberula var. sonorensis) – Easily grown mid-sized fern with dark green fronds arising from creeping rhizomes. Plants, generally about one to two feet tall, make attractive slow-spreading clumps. Grow this fern in partial shade. Excellent container plant.
  • Dudley’s sword fern (Polystichum dudleyi) – Very rarely offered for sale, this is perhaps the most beautiful of our native sword ferns. Plants may reach from 18 inches to 3 feet in height and spread equally wide. In my experience, these plants typically have a much more attractive, upright, vase-shaped growth habit than the broad-spreading western sword fern (Polystichum munitum; we will have this fern for sale, too). Grow Dudley’s sword fern in partial to full shade. Excellent in containers. Throughout gardens in most of our region, this species requires additional summer water.

Ceanothus! We will have a good selection of both species and cultivars of California’s wild lilacs and buckbrushes. One of my favorites is maritime ceanothus (Ceanothus maritimus), and we will have a variety of color forms of this small, low-growing shrub with silvery bark. All of these can be grown as single specimens or as small-scale groundcovers: ‘Valley Violet’ has strikingly lavender-purple flowers and usually reaches about 2 feet tall and up to 3 feet across. ‘Frosty Dawn’ has buttons of deep blue flowers on plants that typically reach 18 inches tall and up to 4 feet across. ‘Pt. Sierra’ has pale-blue flowers and very small leaves on rigid herringbone-branched stems. When not in flower, young plants look very much like non-native rock cotoneaster (Cotoneaster horizontalis). Expect plants to reach a maximum height of 3 feet with a 4- to 5-foot spread. ‘Popcorn’ has pure white flowers with yellow-orange centers and thick, large, grey-green leaves. (It reminded its selector of a full bowl of popcorn, and that’s how the plant got its name.) Expect this dense-growing hemispheric plant to reach up to 2 feet tall and 3 feet wide.

Manzanitas! Our botanic garden grows more species of Arctostaphylos than anywhere else in the world, and our volunteers are always growing a wide array of them for our plant sales. From the rock garden favorite, Hearst manzanita (Arctostaphylos hookeri ssp. hearstiorum), to the rarest of the rare Franciscan manzanita (Arctostaphylos franciscana), to the choice Bert Johnson manzanita (Arctostaphylos edmundsii var. parvifolia ‘Bert Johnson’), our sale features many species that cannot be found for sale anywhere else.

Lupinus formosus! One of the herbaceous perennial lupines, this widespread species can be found throughout the California Floristic Province from northwestern Baja California to the Klamath-Siskiyou region and in the Mojave Desert. The fragrant flowers are typically deep blue to lavender-blue, and though the individual blossoms tend to be small, the flower spikes are freely produced and are very showy. Plants usually grow from two to three feet tall with a narrower spread. In the wild, plants can be found growing in both heavy and well-drained soils. In gardens, be sure to protect the emerging new growth from snails, slugs, and other pests. As with many lupines, caterpillar infestations can quickly defoliate and kill the plants.

These are just a few of the many different kinds of plants that you will find at our spring sale. Be sure to visit the website and see the full list of all plants in the sale. We hope to see you there!

A “Farewell Letter” from Teresa LeYung-Ryan

Greetings to everyone who has experienced or will experience the Regional Parks Botanic Garden:
Teresa LeYung-Ryan here, wishing you wellness and joy.
After twenty-two years, I have retired from the East Bay Regional Park District (EBRPD), the parent organization to the Botanic Garden.
In June 1999, when Botanic Garden Director Steve Edwards offered me the job of half-time Senior Office Assistant at RPBG (aka “The Living Museum”), I had already served for more than three years as full-time Secretary at EBRPD headquarters in the seventeen-person Land/Trails/Advanced Planning Division led by current General Manager Robert Doyle (who at the time was Assistant General Manager for that division). I wanted a half-time job because I had just completed final rewrites of my first book and was building my writing life.
During the past eighteen years, I have been in charge of office operations at the enchanted Living Museum. I used to call myself the “Paper Pusher” (actually, more fitting titles would be “Email Pusher / RPBG Promoter / Advocate for Coworkers and Volunteers”). I have met thousands of visitors and assisted hundreds of couples who wanted to reserve a section of The Living Museum for wedding ceremonies.
Coworkers and volunteers have been asking me: “Teresa, what will you miss most?”
I will miss that quiet, happy feeling, three times a week, when I step into The Garden. You all know the feeling—you could be in any of the ten sections and find yourself smiling.
I wish to thank EVERYONE who has given me joy at this Living Museum. Steve Edwards, thank you so much for hiring me in June 1999.
Here are the names of the dear folks who currently work at the Regional Parks Botanic Garden. I cheer for them. And, I cheer for all the lovely volunteers who will help them at the April 15, 2017 Spring Plant Sale.
Garden Manager Bart O'Brien
Park Supervisor/Horticulture Specialist Joe Dahl
Gardeners Michael Uhler, Liz Bittner, Don Fuller, Theo Fitanides
Interpretive Student Aides Kiamara Ludwig and Chris McCarron
For the Botanic Garden's office line, please call 510-544-3169 and choose "0"
If you’re wondering what my other half-time job has been all these years…
I am Coach Teresa LeYung-Ryan who teaches my clients (writers) how to reach out, not stress out, before and after publication. If you are a writer or have friends who are writers, please visit for resources.
Again, I wish EVERYONE wellness and joy. See you at The Living Museum!  I’ll be smiling—the only difference is, I’ll be a civilian.
