A horticulture community

California Horticultural Society has been dedicated to bringing together gardeners and garden professionals, through meetings and other events, to share their experiences since 1933.


Coffee in the Garden, Sunday, June 5 10 a.m. – 1 p.m.

Members of Cal Hort and Western Hort along with our guests are invited to a Coffee in the Garden event in a San Francisco garden (address will be sent after you RSVP. See below.)

It is short notice but seeing everyone at our first live meeting in two years inspired these members to extend the invite now while their Echium forest is looking good. If you’d like to come please RSVP by email to Mark Delepine and write “RSVP” in the subject line. Please also say which society you are a member of and, if applicable, the number of guests you plan to bring.  (That will help me make sure I bring in plenty of coffee and a selection of teas. You will receive the specific address by return email.


  • This time we’ll emphasize having time for an enjoyable visit with each other and the hosting garden rather than bonus gardens. There is always the SF Botanical Garden and Flora Grubb for those who’d like to extend their visit. 
  • Attendees who can are encouraged to bring a savory or sweet snack to share.
  • Our hosts invite you to bring your own lunch to enjoy in the garden and have graciously volunteered to make a bathroom available for our use. 

Health and Safety: 

The garden is large enough for all who would like to come but you are encouraged to mask up anytime that feels safer for you. Please be sure you and everyone you come with is vaccinated. 

General Meeting (including Plant Forum), Monday, June 20, 6:30 p.m. In-person and live-streamed

Biomimicry of California Native Plants: Interesting Strategies and What We Can Learn From Them

with Lily Urmann, Pratt Institute and Biomimicry Frontiers

Biomimicry is the impactful practice of learning from nature’s forms, processes, and systems to inspire life-friendly design. The incredible diversity of plants that have survived and thrived on Earth for millions of years have already solved many of the challenges we are currently facing. Lily will introduce the topic of biomimicry, showcase examples of biomimetic design, and explain how you too can become a biomimic. We will explore the question: “What can we learn from the interesting and unique strategies of California natives?” by diving deeper into how plants survive drought, capture or store water, prevent moisture loss, protect against wildfire, and build resilience. Once we shift our focus from learning just about different plants to learning from each plant, we can translate these design ideas and build a more sustainable and regenerative future for all. Join us to tap in to Nature’s genius and jump start your own biomimicry journey! 

Supporting Each Other

Plants do not recognize race, economic condition, or social class. Plants can take root in any spot where they can find sufficient sunlight and moisture. Appreciating and nurturing plants can reduce stress, provide food, and promote community.

Nurturing plants can be for everyone, everywhere. Spending time around plants—gardening, spending time in a park, hiking through trees, or playing in a meadow—is good for mental health, promoting relaxation and relief from stress and worries. There are physical benefits to sunlight, fresh air, soothing scents. 

Whether you have a full garden, some house plants, or a few herbs on your windowsill, we encourage you to take time to appreciate the surroundings, smells, and textures, along with sharing your interest with others. Share photos and web links, offer horticultural help and advice, talk to young people about gardening, growing food, and the role plants play in our world. We can help shape the future for good.
