  • Plants include: tomatoes, vegetables, herbs, California natives, drought-tolerant, annuals, perennials, succulents, grasses, trees, shrubs, and house plants. Bring boxes to transport. 
  • Hand Crafted Garden Art.

The sale takes place at the Mariposa Fairgrounds, 5007 Fairgrounds Road at the Amigo Picnic Area.


14th Annual Spring Garden Tour

Be Inspired!

2019 Spring Garden Tour

Please join us on Saturday, May 16 from 9:00 am – 4:00 pm, for a tour of five gardens in Coulterville and Greeley Hill.

This year’s tour revolves around the dual themes of challenge and inspiration. You know the challenges of gardening in our area’s varied elevations, poor soil, hilly land and erratic weather; now find the inspiration to overcome them.

Increasingly, it’s all about the water as we swing yearly between deluge and drought. Explore the use of berms, swales and terraces to tame the deluge on steep slopes. Observe the most effective method of composting and see the abundance it supports.

As you admire the inventiveness of homeowner-designed greenhouses, a farm-to-table garden in a most unexpected place, and some clever ways to thwart birds and deer, you’ll realize that where gardeners are involved no problem is insurmountable.  Persistence and informed practices allow our local gardeners to grow an amazing variety of landscape and food plants that thrive in our hot summers and cold winters. During the tour, knowledgeable docents will be on hand to guide you and answer your gardening questions.

Plan an inspirational Mother’s Day weekend outing and take home great garden ideas by ordering your tickets on-line and pay by credit card. The tour will take place rain or shine.  All participants, including children, must have tickets. Please call us at 209-966-2417 with any questions.

  • $12.00 Advance Tickets;  $15.00 Day of Tour
  • Tickets available at: UCCE Mariposa Office (5009 Fairgrounds Rd., Mariposa CA), Coulterville & Mariposa Visitor Center, Sierra Flowers in Coulterville, Chocolate Soup, or from any Master Gardener

Master Gardener docents will be on hand at each location to answer your gardening questions.  Brochures will be available at each location to guide you through your walk and identify the plants.

Demonstration Gardens

Dark Star & Poppies
Master Gardeners developed and maintain a demonstration garden of California native plants along the path of the Mariposa Creek Parkway on Stroming Road, between 6th and 8th Streets. The purpose of the garden is to demonstrate the beauty and hardiness of California native plants in home landscaping. Most of the plants in this garden are drought tolerant, attract birds and butterflies and are unattractive to deer. Many plant species and varieties are labeled and a brochure for self-guidance is available on-line. Take a stroll down the path and see Flannel Bush, Leopard Lily, Buckeye, Western Columbine, Western Blue Flax, Emerald Carpet Manzanita, Redbud and many others. Funding was provided by the Elvenia J. Slosson Endowment Fund, which is dedicated to the advancement and promotion of the science and practice of horticulture, particularly including ornamental horticulture for the home gardener.

There is a Sierra Nevada Foothills Native Plant Demonstration Garden located at 5039 Fairgrounds Rd. Click here for a Plant Identification Guide to this garden.

Information Booth at the Farmers' Market

Pat & Janette Farmers Market
UC Master Gardeners of Mariposa County man an information booth at the Mariposa Farmers' Market every Wednesday starting in May through October, from 5:00 pm - 6:30 pm. Gardening subjects and displays change each month and coincide with seasonal changes. Located at the Sixth Street parking lot on Stroming Road adjacent to the Mariposa Creek Parkway.

Mariposa County Fair Horticulture Building
Co. Fair scare crows
The Mariposa County Fair Labor Day Weekend is a labor of love for Master Gardeners who perform docent duties in the fruit, vegetable and floral judging building (downstairs from the food judging building) from opening to closing every day of the fair.  Master Gardener docents talk about the displays and answer home gardening questions.

School Gardens

Each year UC Master Gardeners of Mariposa County work with local schools to provide school garden education programs in collaboration with the 4H Junior Master Gardener program and Farm Advisors. The program is tailored to the specific needs of each particular school but generally focuses on planting seeds, appreciating the purpose of beneficial insects, composting and other garden activities.
