In Davis, the original native plant communities were valley grassland, oak woodland, and seasonal riparian woodland.
Besides thriving in our hot summers and alkaline clay soils, native plants support beneficial insects and pollinators of all kinds like butterflies and hummingbirds. Many are medicinal, fragrant or edible.
Until recently, native plant horticulture was a specialized field, but programs such as U.C. Davis Arboretum All-stars are making them more accessible.
If you want to add these plants to your garden, seeing is believing - the following are places in Davis to see California native plants in cultivation and as part of landscapes.
-Ruth Storer Garden at the west end of the Arboretum; a mix of native and non-native species, mostly drought tolerant.
-Gateway Garden behind Davis Commons (Whole Foods), a large planting of native grasses and herbs that come from the same plant communities.
- Mace Ranch Park at 3030 Loyola Drive, a habitat planting of native prairie grasses to provide cover for Burrowing Owl.
-West Davis Ponds and the Butterfly and Hummingbird Garden west of Denali Drive, a well-established collection of natives maintained by Friends of West Davis Ponds.
-Native American Contemplative Garden at UCD Arboretum just south of King Hall, displaying native plants with their Patwin names that were important to First People.
-Urban Greening and Riparian Planting along 1.25 mile reach of the North Davis Ditch, planting of riparian and wetland trees, shrubs, vines and grasses.
-Wild Horse Open Space at the north side of Wild Horse Golf Course, native trees, shrubs and prairie grasses to provide cover for Burrowing Owl.
