CAPIS: California Plant Information Systems is an academic project by UC Davis Landscape Architecture and Plant Biology student Brenna Castro. The CAPIS database is intended for use by California landscape architects, horticulturalists, gardeners, students, and other professionals and enthusiasts to aid in the process of plant selection.

California native plant: a plant that grew naturally in California before 1769, when the first foreign settlers began to introduce and naturalize new species into the California flora.

Site Features

The Plant Search feature allows for identification of plants that meet ecological criteria (climate, soil type, water availability) as well as design criteria (mature size, flower color, plant type). Enter as much or as little information you want, understanding that if the search returns no results, it may have been too specific. A good start for a plant search is USDA or Sunset Zone, as well as plant type (tree, shrub, etc.) to find a general list of plants for your needs.

The List By Name feature allows you to find out more information about a plant whose name you already know. You can choose to see plants listed by family, alphabetically by genus, or alphabetically by common name.

The Selection Criteria page explains the various options you can search by in the Plant Search tool, including links to help you find out your USDA and Sunset Zones, your Jepson Ecoregion, soil types in your area. It also provides definitions or examples of design criteria such as silhouette, drought and pollution tolerance, or growth habit.

The Learn More page provides links to additional information about California Native Plants, including other databases and information sources, lists of native plant nurseries by area, and horticultural guides.
