Promoting Non-Invasive Plants to Protect California’s Natural Beauty, Wildlife and Communities

Invasive plants damage California’s land and impact people. They reproduce quickly—outcompeting native plants and animals, increasing flooding risk, and escalating fire danger. Nearly 50% of all known invasive plants are of horticultural origin. That’s why collaborating with nursery professionals is key to solving this costly problem.

PlantRight unites a diverse alliance of horticultural industry leaders—including The Home Depot in California, Lowe’s, Orchard Supply Hardware, and local, independent garden centers—to protect our state’s unique biodiversity by promoting non-invasive plants. Keeping invasive plants off store shelves means Golden State taxpayers avoid exacerbating the over $80 million annual burden of removing horticultural pests from our wildlands.

Periwinkle is a fast-growing plant that crowds out other vegetation and degrades wildlife habitat.

PlantRight is partnering with leaders in California’s nursery industry to find cost-effective ways to stop the sale of known and emerging ornamental invasive plants and prevent the introduction of new ones to protect California’s unique biodiversity and natural beauty. Key components of our strategy include:

  • Engaging retail nurseries, landscape professionals, and horticultural growers to voluntarily remove known invasive plants from their inventories and replace them with non-invasive alternatives. Learn more here.
  • Preventing the introduction of new invasive plants by deploying PRE (Plant Risk Evaluation), the first WRA (Weed Risk Assessment) tool designed specifically for the horticultural industry that is faster, easy to use, and 98% accurate in predicting invasive behavior by region. The PlantRight PRE equips propagators with the ability to determine a plant’s invasive risk level (to know before they grow) for the region and marketplace in which it is being evaluated.
  • Conducting an annual statewide survey of California nurseries and plant retailers in partnership with the UC Master Gardener Program to assess the availability of invasive plants and guide PlantRight’s strategy in promoting safe, noninvasive alternatives. See the results of our 2014 survey, which shows that more than 80% of the surveyed nurseries were not selling invasive plants on PlantRight’s original list.
  • Providing science-based information to California’s nursery industry that is clear, practical and accessible.
  • Reinforcing positive behavior by recognizing nursery and landscape professionals who are: protecting California’s natural spaces; protecting taxpayer wallets, and Planting Right!
