Lucinda McDade, Judith B. Friend Director of Research at RSABG and chair of the Claremont Graduate University Department of Botany, was a featured speaker at Biodiversity: from Evolutionary Origins to Ecosystems Function. The bicentennial symposium held in October 2012 celebrated the 200th anniversary of research at the Academy of Natural Sciences in Philadelphia.
McDade spoke about the unanticipated uses of museum specimens (including plant specimens). From use of the Lewis and Clark plants to document the chemistry of the atmosphere above the Great Plains in the early 1800s to use of olive leaves in a funerary wreath from King Tut’s tomb along with more recently collected herbarium specimens to document the response of plants to changing carbon dioxide levels, McDade conveyed the message that museum specimens are rich sources of data that will be relied upon to address scientific and societal questions in the future.
In 2011, a panel from the University of Missouri School of Journalism and College of Agriculture, Food and Natural Resources visited Rancho Santa Ana Botanic Garden as part of a state-wide research trip for the Center for Plant Conservation’s publication Dancing with Extinction, a special edition of Plant Conservation, the newsletter of Center for Plant Conservation (CPC).
California is the nation’s second top hotspot for critically imperiled plant diversity (only Hawaii has a more endangered flora). As a charter member of CPC and a major player in the conservation of California plants, RSABG’s efforts to document and preserve the remarkable flora of California were highlighted in Dancing with Extinction.

Dudleya Crassulaceae family
Dudleya is a large genus of about 40 species, many of which are native to California and northern Mexico. Only a handful are common in cultivation and many are on the endangered species list.
At one time Dudleyas were included in the Echecveria genus, which includes the popular garden plant Echeveria ‘Imbricata’ (Hen and Chicks). Like Echeveria, Dudleyas are rosette-forming succulents and are generally silvery green.
However there are distinctions in their flowers. Dudlyea flowers arise near the bottom of the rosettes instead of the center of the rosettes. Most Dudleyas flower in late winter to early spring and the colors range from white and yellow to bright red.
Dudleyas earn their common name of live forever—many living up to 100 years with proper care. They have a wide range, but are typically found in rock outcroppings, cliff faces or steep slopes. Dudleya should be planted at an angle to allow accumulated water to drain from the center of the plant and prevent microbial decay. They are will adapted to the Southern California wet winters and dry summers. Avoid water in the summer. They do well in pots.
This genus is named for William Russell Dudley (1849 - 1911). After Dudley moved to California to accept a position as professor of systematic botany at Stanford University, his research and publishing focused on the diverse flora of California. The study of trees, the evolutionary relations of forms and the problems of geographical distribution were central to his research. Dudley's passion for conifers prompted his involvement in many conservation initiatives for the coast redwood and giant sequoia.
Gloria Slosberg, RSABG Nature Interpreter
Rancho Santa Ana Botanic Garden offers its nature interpreters an infinite variety of constant and ever-changing surprise experiences: like seeing and hearing the loud call of a belted kingfisher perched on a tree at Benjamin Pond, or catching sight of a stunning rust color blossom on a spice bush, or observing a monarch butterfly emerge from its chrysalis.
Miracles similar to these are an everyday occurrence in the Garden. They inspire further study as well as sharing with other volunteers and Garden visitors.
Continuing education is a significant part of the nature interpreter's experience: classes, field trips, event orientations, enrichments, self-study, refreshers, ad infinitum. Joy of learning and friendships that evolve from sharing common interests are enhanced by the energetic, inquisitive children who attend our tours.
At a recent refresher walk, our group stopped to observe a sugar bush. Dick Angus recalled my practice tour nine years ago. You may be able to empathize with my first tour anxiety. I identified the sugar bush as a western redbud. No one said a word; we went on. The next tree was a REAL western redbud with heart shaped leaves and rosy pink blossoms. We all laughed! In that moment, Irv Goldhammer, my mentor, gave me an unforgettable learning tool: patience towards self and others.
What keeps me coming back to RSABG? It is all of the above, plus the uniqueness of each child and adult. On a tour with first graders not long ago, all of us were standing under a California sycamore tree examining its leaves. Then I said," Let's look at the trunk". A little boy, without skipping a beat, asked, "Where is the elephant?"
Thank you, Susanna Bixby Bryant for making all this possible!
Rancho Santa Ana Botanic Garden’s $75,000 Matching-Gift Challenge is Met with Enthusiasm by Garden Donors
Rancho Santa Ana Botanic Garden has come one step closer to its goal of raising $1 million in annual fund donations this year through The Garden Fund, the non-profit’s 2011-12 fundraising campaign. The non-profit organization is celebrating the completion of a $75,000 matching grant which tripled donors’ contributions to The Garden Fund.
Volunteer at California’s native garden—Rancho Santa Ana Botanic Garden.
There are two New Volunteer Orientation, “RSABG 101,” sessions to choose from. Prospective volunteers can choose from two, two-day sessions: Fridays, September 21 and October 5, 9 a.m. to 2 p.m., or Saturdays, September 29 and October 13, 9 a.m. to 2 p.m. Enrollment in the volunteer orientation course requires an interview with the volunteer manager.
Autumn is the best time to plant California native perennials, shrubs, bulbs and wildflower seeds.
Since native plants have spent generations adapting to local growing conditions, they are great additions to home landscapes—and one that can save you time and resources. Native plants are rarely invasive. They support local wildlife—birds and butterflies depend on them for food shelter and nesting. And most of all they are beautiful.
Undergraduate students have come to Rancho Santa Ana Botanic Garden for a plant systematics and evolutionary biology workshop August 11 through 21, 2012.
The workshop offers students a hands-on plant science learning opportunity—from collecting and making plant specimens to DNA extraction to working with the scanning electron microscope to analyzing the data that result from such a project.
Students have come from colleges and universities in Indiana, Arkansas, Texas and Southern California, as well as international students from Namibia and Venezuela. Professors Lucinda McDade and J. Mark Porter are leading the workshops and Kristen Hasenstab-Lehman, CGU doctoral candidate, is serving as the teaching assistant.
The intensive 10-day workshop will focus on the types of research questions and methods used in reconstructing evolutionary relationships in plants. Topics to be covered include: DNA extraction and sequencing methods, scanning electron microscopy, anatomy and morphology, field collection techniques and herbarium curation. Participants will learn to use Internet tools (e.g., GenBank) and software packages to gather, process and analyze phylogenetic data.
The workshop is made possible through funding provided by the U.S. National Science Foundation.
Botanic Gardens Conservation International (BGCI) has ranked Rancho Santa Ana Botanic Garden’s oak collection as 28th largest collection of rare or endangered oaks in the world.
The survey identified 3,796 oak records from 198 institutions in 39 countries. RSABG’s collection of oaks was deemed a significant botanic garden collection by assigning a score for each taxa within the garden’s collection and the number of unique or rare collections.

The intention of “Processing Seeds of California Native Plants for Conservation, Storage, and Restoration,” by Michael Wall and John Macdonald might be encapsulated with the well-placed quote in the manual’s brief preface.
The editors selected an excerpt from the U.S. Dept. of Agriculture’s 1961 “Seeds, The Yearbook of Agriculture,” that concludes with an apt description of the humble seed’s purpose—“Seeds are containers of embryonic plants, the embryos of a new generation.”
The beauty of California lies not only in our remarkable flora, but in its people as well. For the indigenous peoples of the region, native plants often became cultural pillars.
The gift shop at the Garden is now featuring traditional willow and wiregrass baskets and clay pottery hand made by Pai Pai and Kumeyaay Indians tribes in Baja California, Mexico.
