Water-Wise Plant Lists

If you are choosing plants for the CCWD Lawn to Garden Rebate Program, they must be either listed in the Contra Costa Water District’s List of Approved Plants or are rated either “low” or “very low” in the WUCOLS Plant Database. Plants not on the list will be approved on a case by case basis.

If you are simply looking for water-wise plants, use any one of the following websites to help you research water-wise plants.

Contra Costa Water District’s List of Approved Plants

All of the plants on this list (PDF) are approved for use in our Lawn to Garden Rebate Program. Not all of the plants on this list are right for every garden, so please be sure to talk to your local nursery, or use the following resources to find specific information about a plant’s mature size, preferred sun exposure and other needs (like soil type and drainage).

WUCOLS Plant Database

This is a
plant database that you can look up a plant by either common name or botanical name.  The plants are rated by their water use:  high, medium, low and very low.  Any plants that are rated “very low” or “low” are acceptable for the Lawn to Garden Rebate Program.

If you have plants that are not listed on either the CCWD List of Approved Plants and WUCOLS Plant Database, please check with CCWD to have them reviewed for approval.  Email the plant names (botanical name if possible) to conserve@ccwater.com.
