The choice of plants for landscape use along the Wasatch front is extensive and new plants are continually being tried, particularly at Red Butte Garden and Arboretum. The Utah Nursery and Landscape Association carries an extensive palette of trees, shrubs, vines, groundcovers, perennials, ornamental grasses, and seasonal annuals and vegetables. Many native plants are now carried by member nursery outlets. For reliable professional help you should consult with certified nursery personnel. Park City residents would do well to use zone 3 and 4 rated landscape plants.
Summer rains are few and far between.
The growing season is relatively short, with the last frost about May 7 in the spring and the first frost about October 17 in the autumn. Earlier and later frost or even snows are possible. Both of these programs are free with paid garden admission fee and address a variety of gardening topics with area experts. A members-only sale is held the previous day. Staff and volunteers are on hand to help you select plants for your garden.
