PlantRight Takes Time Out on Survey in 2018

February 1, 2018

Last year marked the 8th year of PlantRight’s annual Spring Nursery Survey, and thanks to a large number of UC Master Gardener volunteers, as well as volunteers from other organizations, it was a huge success! The UC Master Gardener Program and its volunteers have been a key partner since the inception of the survey in 2010, and make up most of our volunteer base. Farther afield, volunteers from the California Native Plant Society, Association of Professional Landscape Designers, Imperial County Agricultural Commissioner’s Office, and Siskiyou County Department of Agriculture help by surveying nurseries in more remote areas.

2017 by the numbers:

  • 172 volunteers
  • 332 garden centers
  • 45 counties


According to the 2017 Spring Nursery Survey Fact Sheet, the rate of nurseries selling invasive plants continues to decline. In 2014, 44% of nurseries surveyed were selling locally invasive plants; this rate dropped to 35% in 2015, to 31% in 2016, and 29% in 2017.

Of the nurseries that were selling any invasive plants in 2017, only 8% had more than one species of invasive plant for sale. This is down from 2016, when 10% of stores (that sold any invasive plants) had more than one invasive plant for sale.

No Spring Nursery Survey in 2018

PlantRight will not be conducting the Spring Nursery Survey in 2018. This one year break from the survey allows us to make a more concerted statewide outreach effort to landscape professionals (e.g. architects, designers and contractors), and the most influential water districts promoting sustainable landscaping. Successfully engaging these professionals and districts will accelerate our work to keep invasive plants off California wildlands and promote climate appropriate alternatives. That’s because these groups have significant influence on the nursery supply chain — what horticultural growers grow, what plants get specified in landscape design, and the plant material that contractors source. Engaging water districts is a cost effective way to educate members of the gardening public, especially those interested in replacing thirsty lawns with lovely looking, climate appropriate landscape plants.
