Nordic Gardens has 5 major cold frames on its Carbondale Colorado location. We keep a constant supply of our favorite hardy mountain perennials we have selected from our 30 years building specialty gardens in Aspen and Snowmass Colorado. Most commercially grown nursery plants are sold for their quick color appeal. You will find the most will not survive the summer due to pests, or our harsh mountain environment. Nordic Gardens produces proven hardy high altitude acclimated varieties of perennial flowers. Nordic produces a broad range of mostly Colorado native plants that are extremely hardy and pest proven varieties.
