Join us for monthly Western Hort programs designed to inform, educate and inspire the dedicated plant lover. Meetings are currently available via Zoom and links are sent monthly to all members who provide email contact information. Meetings are a benefit of  WHS membership. We also currently have a sharing agreement for meetings with the California Horticultural Society. Our members will receive links to the their monthly Zoom meetings and we will send them links to ours.

Meetings are held 9 times a year on the second Wednesday of the month and feature a lecture and slide presentation by a guest horticultural specialist. Each program also includes a member-led discussion and photos of unusual plants.

Future in-person meetings, when feasible, will be held at the Garden House in Shoup Park, 400 University Ave, Los Altos.

Located near Lincoln Ave.

In-person meetings often include a sale of diverse plant varieties donated by members and local nurseries as well as books, seeds, tools and other horticultural items on occasion.  All are welcome!

Year-round Color With Native Plants

With Madeline Morrow

Enhancing biodiversity can be beautiful. Learn how to select and group  plants with varying bloom times so your garden is never without color. See  how to choose different plant forms and include beautiful bark, berry, and  seed producing species for maximum interest all year long. You’ll enjoy  your garden in every season and so will the bees, butterflies and other  insects, lizards, and birds!


Madeline Morrowis a past President for the Santa Clara Valley Chapter of California Native Plant Society, and current board  member. A former computer programmer, she now volunteers in her community and works extensively on her native garden. Her garden  was featured in Bay Nature magazine in March 2013. She is an avid  gardener who switched her focus to native plants in 1993 when she  learned how essential native plants are for wildlife, first in upstate  NY, and then in California. In her current garden she has learned a  lot about gardening on heavy clay and strategies for drainage  problems and retaining rainwater. These include installing a rain  garden. Her garden is usually on the CNPS-SCV Growing Natives  Garden Tour because she is passionate about spreading the word  about native plant gardening.

Farming in The Valley of Heart’s Delight

With Andy Mariani and Charlie Olson moderated by Robin Chapman

Change is inevitable. But despite the paving over of The Valley of Heart’s Delight,

many of us still cherish the legacy of the farmers and bounty of the harvest of Santa Clara Valley.

This is still one of the best climates on earth for growing an amazing variety of fruit.

Between the two of them, Charlie Olson (in Sunnyvale) and Andy Mariani (in Morgan Hill)

have spent over a century tending family orchards and growing some of the

best tasting fruit there is.

Tonight Robin Chapman will moderate a conversation between two local growers whose skill, knowledge and passion has kept some precious acres of trees growing and producing fruit

with the flavor they were meant to have.

This conversation will be in a question and answer format. Members are asked to submit their questions for the speakers at least a week before the meeting to  info@westernhort.org.


Andy Mariani, educated in both horticultural and behavioral sciences, continues his family’s tradition of growing specialty stone fruit along with persimmons and citrus in Santa Clara County. 

An innovative farmer, he practices Integrated Pest Management as an approach to fruit growing. 

As a member of the California Cherry Research Committee, he has helped initiate research in cherry growing.  He has also authored a book on fruit varieties, several articles and lectures on various aspects of fruit growing. 



Charles J. Olson grew up picking apricots and prunes in the family orchards in Sunnyvale, land his grandfather first purchased in 1899. His mother Rose, an immigrant from the Middle East, set up the family’s first fruit stand on El Camino Real.

Charlie went off to the University of Denver where he played football. After college Charlie played professional football in the Canadian league and then returned home to become the third generation of Olsons to work in the family business. Charlie’s daughter Deborah, the fourth generation, now distributes his luscious fruit through their family company, C.J. Olson’s Cherries. Charlie, now 86, manages the 10-acre Sunnyvale Heritage Orchard, one of the last working apricot orchards in the Santa Clara Valley. He was recently named "Sunnyvale's Hero," an honor marked by a banner in the orchard he has long cared for. 


Robin Chapman is a journalist native to Los Altos, California. She worked at KRON-TV in

San Francisco and several other stations in the West before heading to Washington D.C.

There she covered the White House and other big stories for the ABC-TV station. In 2009 Robin returned to her hometown to care for her parents, and in the years since has published

California Apricots: The Lost Orchards of Silicon Valley and Historic Bay Area Visionaries,

both from the History Press.

She is working on a book based on a collection of her columns for the Los Altos Town Crier on Bay Area history. It is tentatively titled Apricots in Paradise: True Tales of the Santa Clara Valley and scheduled for publication by History Press in late 2022.
