  • Choosing plants that will thrive in your specific site
  • Work in Extension's Plant Elements of Design plant selection database to try out your new knowledge on your own landscape
You will leave the class with increased confidence to make plant choices in your 2020 garden, and an understanding of tools that are available to help!
