Native Plants

Create a natural landscape in your yard that needs less watering and fewer chemicals and is resistant to pests and diseases. Native plants also attract birds, butterflies, and beneficial wildlife to your yard while reducing erosion and protecting water quality.

Plan Your Planting

  • Remove Non-Native Invasive Plants
  • Use a Native Plant Finder to choose appropriate plants.
  • Plant at these density standards to establish a healthy plant community:
    • square footage x 0.01 = number of trees
    • square footage x 0.05 = number of shrubs
