Many mountain areas in Colorado have many deer. Gardeners often must battle the deer over decorative plants that deer find delicious. By selecting plants that deer don't like, you can create a shade garden that won't be devoured by deer. In most cases, plants that are deer resistant are also rabbit resistant.
