Sue Cruth Memorial Plant Select Demonstration Garden

Plant Select® is a cooperative program administered by Denver Botanic Gardens and Colorado State University in concert with horticulturists and nurseries throughout the Rocky Mountain region and beyond. The purpose of Plant Select® is to seek out, identify and distribute the very best plants for landscapes and gardens from the intermountain region to the high plains.

Summit County Master Gardeners have worked hard to create a beautiful Plant Select Demonstration Garden at the Sue Cruth Memorial Garden at the County Commons in Frisco. Please stop by to check it out! The County Commons is located at 37 Peak One Blvd. (County Road 1005).
