Acorn Festival - November 19


Sunday, November 19, 11 a.m.-3 p.m.

Fall is a time of harvest and festivities for the people of Southern California, as acorns from the live oak (Quercus agrifolia) were traditionally an important major food source. In honor of this, Native American dancers and tribal leaders join us to celebrate our connections with California native plants. (Dancers will demonstrate various dances intermittently throughout the day.) There will also be an artisans' marketplace. 

The Acorn Festival takes place rain or shine!

This event is free with Garden admission. Some activities require a small materials fee.

Kendall Johnson: Johnson's Pasture: Living Place, Living Time - July 22 through November 1

Kendall Johnson:

Johnson's Pasture: Living Place, Living Time 

July 22 through November 1

An acclaimed artist with deep roots in the Claremont community, Kendall Johnson’s work explores memory through modes of artmaking that are at once sensual and bold. His paintings, photographs and poetry often appear as wayfinding compositions, maps to points that are both known and unknown - a rerouting through one’s own personal history in a quest for both answers and new questions.

For his solo exhibition at the Garden, we have curated with Johnson a selection of his works from his series on Johnson’s Pasture. Those who encounter Johnson’s Pasture in the foothills north of Claremont find themselves in a wildland located between worlds, from the glimmering cityscape below to the towering San Gabriel mountains that rise dramatically above. An integral part of Claremont’s history, Johnson’s Pasture was purchased over half a century ago by Johnson’s great grandparents. This special place is a geophysical family tome to Johnson, imprinted with four generations of memories - including groves of carefully tended eucalyptus and pine trees, to worn paths made by family forays into the hillside that offered contemplative retreats from daily life. Now part of the Claremont Wildlands Conservancy, it stands as a testament to the beauty, value and necessity of wild space - where California native wildlife can thrive, including humans.

In this series, the artworks search through Johnson’s decades’-long relationship to the Pasture. They are invoked from distinct chapters of Johnson’s life when the meaning of Johnson’s Pasture and its wilderness meant different things: before and after serving in the Vietnam War, raising a family, serving as a crisis-management consultant during the tragedy of 9/11. Each distinguished piece draws on the solace that Johnson’s Pasture provided in these times. They speak to the power of wild as a restorative force, both for the very real ecological habitat it provides, as well as the emotional centering it offers when we feel lost.

Gallery open to the public daily, 10 a.m. - 4 p.m.  Admission to the gallery is included with standard admission or membership.

Special opening reception for RSABG members on Friday, July 21, from 5 p.m. to 7 p.m. RSVP requested: please RSVP to the Advancement Office, (909) 625-8676 ext. 221, or This email address is being protected from spambots. You need JavaScript enabled to view it..

Library Exhibition: Wildflowers of the Western Deserts: The Photographs of Lustin E. Martindale

lm wf xs

Lustin E. Martindale (1886-1950) grew up in Indiana and settled in the Pasadena area of California in 1907. Martindale was a naturalist, photographer, and educator of art within the California State school system. He was known for his hand-tinted glass slides of California flora, which he sold commercially. He published his glass slides in book format in his photograph sales catalogs, as with The Wild Flowers of Southern California (1926), which includes seventy-one pages of his photographs.  Likewise, the Wildflowers of the Mojave and Colorado Deserts (1927), which is part of the Rancho Santa Ana Botanic Garden Library Special Collections and featured in this exhibit, lists item numbers of slides and photographs available for purchase. Martindale’s photographs have been published in numerous journal publications such as American Art Annual, Western Nature Science Series, as well as in An Illustrated Manual of California Shrubs (1939) by Howard E. McMinns.

The Martindale hand-tinted photograph prints on display in this exhibit are part of the Rancho Santa Ana Botanic Garden Library Special Collections. The RSA Library Special Collections holds one-hundred and one of Martindale’s photograph prints as well as well over one-hundred of his hand-tinted glass slides of plants and flowers.

The Rancho Santa Ana Botanic Garden Herbarium holds six plant specimens that Martindale collected between 1880 and 1928. Two of the Martindale specimens within the RSA Herbarium are types from the Liliaceae family (Lily): Fritillaria ojaiensis, photographs of which are featured here.

Wildflowers of Western Deserts; The Photographs of Lustin E. Martindale is curated by Brandy Watts, MFA, MLIS.

The Rancho Santa Ana Botanic Garden Library is open Monday through Friday 9am-5pm.
