There are now fourteen distinct gardens to visit at the Master Gardener Demonstration Garden at Patrick Ranch. Once the final two themed gardens have been planted, the overall master plan will be fulfilled. But don't say the Demo Garden is “finished.” As Kay Perkins, the visionary behind this project, says: a garden is never finished.
- Backyard food gardens
- Sustainable gardening practices
- Conserving water
- Protecting and nurturing soil
- Protecting water and air quality
- Reducing waste to the landfill
- Reusing and recycling
- Creating wildlife habitat
The various phases of planning, installing infrastructure, and planting (and replanting) the Demonstration Garden have provided the Master Gardeners (MGs) involved in this project with quite an education, as will be detailed below. But first -- a little history. The charter class of the Butte County MGs graduated in June 2008. Perkins was a member of that class, and from the beginning she believed that a Demonstration Garden would be a wonderful teaching tool. The Patrick Ranch Museum was eager to partner with the MGs and has continued to support the project. (For more about the Patrick Ranch Museum and its mission, see Patrick Ranch Museum).
As is true with any garden, particularly one as ambitious as the MG Demonstration Garden, lessons were learned along the way. The Demo Garden is located in the middle of a working orchard, 28 acres of a heritage Butte County ranch that are preserved for teaching historical agricultural practices. So, not surprisingly, the very first of the themed gardens, the Butte All-Stars Garden, was planted in a different environment than that of most home gardeners. The location of the All-Stars Garden – in front of the Patrick Ranch Museum Gift Shop – brought with it a lot of public traffic, high visibility, and inevitable scrutiny. At the beginning this area had essentially no shade, and the soil had been impacted (and, in some areas, compacted) by previous orchard practices, including the operation of heavy machinery.
All of the themed gardens that comprise the Demonstration Garden showcase what can and/or should be planted in our environment. The last couple of decades have brought increased pressure from drought, and we want to demonstrate how we can all adjust our aesthetics and pivot to a kind of gardening that is sustainable, yet still beautiful and functional. Therefore, our plants (except for some of the edibles), are low (or no) water perennials, and all of them are either Mediterranean or California natives.

Master Gardener volunteers partner with County of San Diego on new demonstration garden
In a garden with roughly the square footage of a two-car garage, the University of California Master Gardeners and County of San Diego staff have packed a whole lot of learning for the community.
The demonstration garden, which had its grand opening last fall, is now flourishing in its 20-by-20-foot space in a plaza at the heart of the San Diego County Operations Center. Skilled volunteers with San Diego's UC Master Gardeners, a program of UC Agriculture and Natural Resources, maintain its containers of vegetables and herbs, succulents, and native and pollinator plants.
“For such a little garden, there's a lot to look at,” said Karen Morse, a Master Gardener volunteer who helped establish the “demo garden” – a highly visible and accessible teaching tool for the many people who work and conduct business in the surrounding offices.
“We get questions from people just walking by – from the public, from county employees – all the time,” said Leah Taylor, UC Master Gardener program coordinator in San Diego County. “While we're doing what we're doing in the garden, we're a presence for people to just get a quick bite of education.”
The garden also features a “Little Free Library” of gardening books, as well as a compost bin and rain barrel for demonstration purposes. There are also signs (in English and Spanish, as well as additional languages on the garden's website) offering tips on composting/worm composting, pest management, water conservation, climate adaptation, sustainability practices, and health and nutrition. The expertise of a host of county departments and agencies inform the resources.
“The most beautiful thing about that garden is not necessarily the plants – although we love our plants – it's that it showcases almost every county department…all represented in one place and you can find how to connect with those groups, all in one place,” Taylor explained.
During planning for a broader revamp of the Operations Center grounds, the county had approached the Master Gardeners to provide guidance on a public demo garden.
“The County has a long-standing commitment to sustainability and partnership with the University of California Cooperative Extension,” said Rebeca Appel, program manager for the county's Land Use and Environment Group, which spearheaded the effort through the “Live Well San Diego” Food System Initiative. “So it was a natural approach to work with the Master Gardeners with their robust community garden program, and educational outreach in home and urban gardening throughout our region.”
The vision for the garden was shaped by county teams working with Joan Martin and Ellen Cadwallader, co-chairs of the Master Gardener committee that oversees the program's demonstration gardens across San Diego County, including those at Balboa Park and The Flower Fields in Carlsbad.
And while those gardens help raise awareness among the many visitors at those sites, Martin said the newest demo garden provides unique opportunities for ongoing community education, such as lunch-and-learns on specific gardening topics.
“This is the garden where there's really a chance for year-round education and sessions,” Martin said. “We're excited to see it get started and watch it grow.”
Morse and fellow Master Gardener Sandy Main collaborated with Appel to bring those early plans and objectives to verdant life.
“I think we ticked all the boxes of everything they wanted, initially – examples of container gardening, natives, vegetables, herbs, pollinators – and wheelchair accessible,” Morse said.
They have since passed the botanical baton to Skye Resendes, a relatively recent graduate of the Master Gardener certification program. She will coordinate a team of a dozen volunteers in the ongoing upkeep of the County Operations Center demo garden.
Resendes, who uses gardening to help her cope with the stresses of her work as a civil litigator, said she hopes the garden will not only inform the community on crucial ecological and conservation topics but also inspire more people to start their own gardens.
“The science is out there – there are huge mental health benefits to gardening,” Resendes said. “It's an absolute meditation.”
/h3>“Native plants give us a sense of where we are in this great land of ours. I want Texas to look like Texas and Vermont to look like Vermont.” — Lady Bird Johnson (First Lady of the United States as the wife of President Lyndon B. Johnson, 1963 – 1969).
Plants define the landscape. In California, besieged by the twin threats of drought and wildfire, the choice to grow native versus non-native plants is attracting more attention than ever before. What exactly are the merits of native compared to non-native plants, and how do gardeners make the best choice about what to grow in a home garden?
Native plants occur naturally in the area where they originally evolved. These plants have coevolved with wildlife, fungi, and microbes, and their interdependent relationships form the foundation of our native ecosystems (Native and Naturalized Plants for the Home Garden in Northern California, p. 1).
With this stunning variety of native plants, you might expect to see them growing on every corner and offered for sale in every nursery and home improvement store, yet this is not the case. In fact, according to the California Academy of Sciences, 75% of the original native plant habitat in California has been lost (Hotspot: California on the Edge, p. 2).
Since California natives are less commonly planted compared to non-native plants, you can become more familiar with them by visiting a local native plant garden such as the Butte County Master Gardeners Demonstration Garden at Patrick Ranch in Durham, the Alice B. Hecker Native Plant Garden at Chico Creek Nature Center, and the Native Plant Pollinator Garden at Gateway Science Museum in Chico.
But how do we know for sure that a plant really evolved in the local area? Botanical studies of the world's flora have been ongoing for many years, and the historical record includes many specimens and drawings of plants that were originally brought to America by European explorers and settlers. In addition, paleobotanists have been able to compare fossil records with modern plants to accurately identify which plants are native to an area (Native and Naturalized Plants for the Home Garden in Northern California, p. 2).
Another advantage to native plants is that once they are established, they normally need little watering beyond normal rainfall. With California experiencing an historic drought, native plants can help save significant amounts of water that would otherwise be soaked up by thirstier landscape plants. In general, native plants require less maintenance than non-native garden plants: less water, little or no fertilizer, less pruning, less of your time.
In addition, California native plants attract wildlife that use these plants as their natural habitat. For example, the many pollinators that flock to native plants can improve fruit set in your home orchard and yield in your vegetable garden. A variety of native insects and birds can reduce populations of mosquitos and plant-eating bugs. By using native plants, you support native wildlife and help preserve the balance of natural ecosystems (Benefits of California Native Plants).
“California has the greatest natural botanical diversity of any state in the United States. In addition to nearly 5,000 native plant species, there are about 1,500 non-native species that have become established in the state. About 250 to 300 of these are weeds of agricultural crops, turf, or gardens. The remaining 1,200 or so are naturalized plants of wildlands or disturbed non-crop areas, some of which are important invasive plants” (UC IPM Pest Notes: Invasive Plants).
Invasive plants can “disperse, establish and spread without human assistance,” and they cause disruption of natural ecosystems. The worst invasive species are called landscape transformers because they substantially alter the “character, condition, form and nature of the invaded habitat,” consuming resources needed for native plants to survive. When invasive plants replace native plants in the wild, wildlife that feed on the native plants suffer and may become endangered. (UC IPM Pest Notes: Invasive Plants, pp. 1-2).
Home gardeners may be surprised to learn that commonly available plants such as periwinkle (vinca major), or butterfly bush(Buddleja davidii), are listed on the California Invasive Plant Council Inventory, as are sweet alyssum (Lobularia maritima), and gazania daisy (gazania linearis). Periwinkle, English ivy, Himalayan blackberry, and Chinese pistache, among others, have invaded our own beloved Bidwell Park. You may be dismayed to realize that you are growing invasive plants in your own garden! The University of California's division of Agriculture and Natural Resources has information on how to determine whether a plant in your garden is safe to keep or should be removed (UC IPM Pest Notes: Invasive Plants, p. 7). The potential for a plant to spread from your garden to surrounding natural areas is a critical consideration in deciding whether to keep an invasive plant or destroy it.
When you shop for plants, “the key element is to know which horticultural plants are invasive in your area of the state. If a plant is listed as invasive in your region, it should be avoided for landscape use, especially for locations near natural areas. It may be safe to use in other regions, but sometimes the plant is not listed as invasive in an area merely because it has not yet become a presence” (UC IPM Pest Notes: Invasive Plants, 7).
Another fine resource for Butte County gardeners interested in planting responsibly is the list of Butte County All-Star Plants developed by the Master Gardeners and based on their experience at the Demonstration Garden at Patrick Ranch. These are plants that grow well in the local area. Almost all them are drought tolerant or require only moderate watering, and some are also California natives.
Gardeners interested in planting California native plants will appreciate the CalScape website where you can enter your address and search for plants that are native to your area. The search results are categorized in useful ways including low/very low water, butterfly hosts, very easy to grow, shade/part shade, annuals, perennials, and more. The information on each plant also details how the plant provides habitat for wildlife.
Clearly, home gardeners can support the health of natural ecosystems and conserve water in California by making wise choices about landscape plants. With non-native plants, make sure a plant is not invasive (or potentially invasive) before purchasing it, and be aware of its water requirements. Ultimately, California native plants are the best and most responsible choice, especially because of the ongoing drought and their diminishing natural habitat. The one drawback of native plants, perhaps, is that they can be harder to find; fortunately, the Butte County Master Gardeners program offers twice yearly plant sales featuring native plants at reasonable prices. One native plant at a time, home gardeners can help “California look like California” again in all its marvelous biodiversity.
