Trust Our Land: Harrington’s Penstemon – A Unique Flower That Calls Eagle County Home

by Bergen Tjossem

Eagle Valley Land Trust conserves land for several reasons. We work to protect working agricultural lands to provide local food and fiber to our community. We also conserve open space to protect majestic views, recreation opportunities and historical significance. Additionally, we work with local partners to identify and preserve critical habitat for local plants and animals.

For many, summertime in Colorado evokes images of vibrant vegetation and beautiful flowering plants carpeting our landscapes. One of the rarest and most fascinating of these plants is Harrington’s Penstemon (Penstemon harringtonii). Have you ever spotted one? Please join Eagle Valley Land Trust for our free, guided hike on Saturday, June 11th from 8:30-10:30 to explore the 478-acre West Avon Preserve conservation easement in search of Harrington’s Penstemon.

Harrington's PenstemonHarrington’s Penstemon has 12 to 18 flowers per plant and is a mixture of hot pink, purple and light blue. It is most often found flowering in June and July in dry, sagebrush landscapes between 6,400-9,400 feet on all aspects. For unknown reasons Harrington’s Penstemon has not been found in any other place in the world except six counties in Colorado (Eagle, Garfield, Grand, Pitkin, Routt, and Summit) and documented in only 74 locations, totaling an estimated 43,000 plants. Of its 74 documented locations, 50 locations are found in Eagle County. It’s an incredibly rare flower, and we are very fortunate to have the most documented Harrington’s Penstemon right out our back doors.

Eagle Valley Land Trust holds seven conservation easements, totaling over 2,500 acres of potential Harrington’s Penstemon habitat, thus protecting this sensitive habitat forever. These elusive and beautiful flowers have been documented on four of those seven conservation easements. EVLT is working to sustain this rare and beautiful flower for our future generations to enjoy.

Unfortunately, Harrington’s Penstemon are under constant threat of disappearing. Habitat loss due to development is all too real; motorized and non-motorized recreation impacts the fragile soil; invasive, non-native weeds steal vital nutrients and already scarce water from these delicate flowers; picking these beautiful flowers for gardens and bouquets eliminates their reproductive capabilities; and climate change will inevitably have impacts on the flower.

So, why should you care to sustain this gem of Eagle County and Colorado?

Harrington’s Penstemon is unique to Colorado, and specifically the Rocky Mountain region. The variety of beautiful wildflowers is one of the things that makes the Colorado Rockies so spectacular. Protecting Harrington’s Penstemon means protecting plant diversity, which in turn protects bird and wildlife diversity. Native animals have devolved to depend on specific native plants for food. Each species in a natural area has an important job to do. It is important to protect native plants and animals in order to protect the character of this beautiful place.

Understanding the significance of this flower for our community, Eagle Valley Land Trust is offering a free, guided hike on Saturday, June 11th to explore the 478-acre West Avon Preserve conservation easement to search for Harrington’s Penstemon. The hike will start and finish at the June Creek trailhead, beginning at 8:30AM and finishing around 10:30AM. The hike is capped at 30 participants, so please RSVP as soon as possible to reserve your place either by calling (970) 748-7654 or emailing jfoulis@evlt.org. Additionally, there are a variety of organizations in the county that offer guided wildflower hikes and identification classes throughout the summer such as the Betty Ford Alpine Gardens, and Walking Mountains Science Center.

If you are interested in protecting habitat for the plants and animals who call the Eagle Valley their home, please support the Eagle Valley Land Trust and our mission to preserve forever our scenic vistas, open space, historic lands, waterways, and wildlife habitats that represent the uniqueness of Eagle County and the Rocky Mountains for the enjoyment, education, and benefit of all who experience this special place. With your support, we can all work to protect the native plants of our Rocky Mountain summer.
