Santa Clara Valley Water District Landscape Rebate Program Qualifying Plant List Following is the current Santa Clara Valley Water District (SCVWD) Landscape Rebate Program Qualifying Plant List. The list is based on the WUCOLS IV 2014 Edition, published by the University of California Cooperative Extension and the California Department of Water Resources, as well as input from several botanists that work in Santa Clara County. WUCOLS stands for Water Use Classification of Landscape Species, and is a guide that provides evaluated water needs for more than 3,700 plant species in California. All of the plants on the Landscape Rebate Program (LRP) Qualifying Plant List are considered low or very low water using plants in Region 1 according to the WUCOLS guide. Highly invasive plants have been removed from the list. Customers are required to select plants from the following plant list in order to meet the minimum 50% plant coverage requirement for the Landscape Rebate Program. Plant coverage values are calculated based on the mature size of the plant. The value is obtained by determining the area of a circle using the plant spread or width as the diameter. To find the area of a circle, square the diameter and multiply by .7854. Squaring the diameter means multiplying the diameter by itself. For example, a plant with a 5 foot spread would be calculated as follows: .7854 x 5 ft diameter x 5 ft diameter = 20 sq ft (values are rounded to the nearest whole number). The coverage values have been predetermined for most of the plants listed on the LRP Qualifying Plant List. For values not provided, please refer to reputable gardening books or nurseries in order to determine the diameter of the plant at maturity or contact the SCVWD for assistance. Plants included on the LRP Qualifying Plant List that are listed by the genus name only (i.e. Ceanothus ssp.) indicate that every species and every cultivar of that plant is considered low or very low water using and each species would qualify toward the 50% plant coverage requirement. If you are planning to install one of these plants, please include the entire name of the plant (genus, species, and cultivar) on your plant list. If you need additional information or would like assistance in determining the plant coverage values, please contact the Santa Clara Valley Water District Water Conservation Hotline at (408) 630-2554 or email [email protected]. Plants noted as Potentially Invasive on the list below have the potential to spread aggressively. It is best not to plant these plants adjacent to [within 5 miles of] wild land, state/county/city parks, open space preserves, creeks, lakes or drainage ditches. (Highly invasive plants have already been removed from the Qualifying Plant List). Plants noted as Genetic Concern are plant species or cultivars that are within a genus which may be native to Santa Clara County. Consult a plant ecologist or native plant database to determine if your landscape project is located within 5 miles of wild populations. If so, please follow these suggestions to protect local genetic integrity: 1) select a local ecotype 2) avoid use of cultivars or hybrids, especially those with non-local or unknown parentage and 3) avoid use of nonnative ornamentals which share the same genus in order to prevent unnatural hybridization.
