Berthoud-based Northern Colorado Water Conservancy District (Northern Water) has a long history of facilitating water efficiency through studies, its Conservation Gardens and industry certification classes. Yet, increased demand for landscape water efficiency assistance has driven Northern Water to expand its support of the green industry and efforts to enhance landscape water use and value. After collaboration and stakeholder feedback, Northern Water identified opportunities to help water users manage their water better. Created in 2017, the Water Efficiency Program now offers multiple, complementary solutions to build more capacity for efficient water use in the region.

Each of these perennials has been in the garden for several years and, year after year, each has shown adaptability to the area.
