The Wenatchee Larkspur (Delphinium viridescens) is a rare plant native to the U.S., located in the Wenatchee Mountains region, and is a part of the Ranunculaceae family.[1] The Wenatchee Larkspur is generally described as a perennial forb/herb.[2] The scientific name of the Wenatchee larkspur is Delphinium viridescens, which is a native plant to the United States, located in the mountains southwest of Wenatchee, Washington.
Established in 1989, the Nature Conservancy purchased land parcels located in eastern Washington to protect one of the "last best places" on earth.[3] The Camas Meadows Natural Area Preserve contains the largest known populations of two rare plant species, the Wenatchee Mountains Checker-mallow (Sidalcea oregana var. calva) and the Wenatchee larkspur. These plants grow only in the Wenatchee Mountains region, they are not found anywhere else in the world.

Flower description
The Wenatchee larkspur is a plant native to the mountains southwest of Wenatchee, Washington. Flowering season is in the summer, most notably in July; peak anthesis occurs during mid-summer. Fruits of the Wenatchee larkspur mature and begin dispersal by late September.[4] The Wenatchee larkspur is located primarily in wet meadows and stream sides in coniferous forest, and heavy clay soils.[5]
Camas Meadows Natural Area Preserves
In parts of Washington, almost all of the landscape has been altered. As eastern Washington's population is growing, its natural landscape is rapidly disappearing. Through Natural Area Preserves the Department of Natural Resources (DNR) protects remnants of Washington's natural heritage, reconstructs habitat and contributes to a healthy environment for future generations. Natural Area Preserves are set aside for research and provide opportunities for education. Many require a DNR guide, but others have interpretive trails where anyone can learn about Washington's unique natural heritage on their own.[6]
The Natural Area designation at Camas Meadows was purchased primarily to protect two endangered plants that live there: the Wenatchee larkspur and the Wenatchee Mountain checker-mallow. The Preserve at Camas Meadows contains 75% of the global population of the Wenatchee Mountain checker-mallow and 40% of the Wenatchee larkspur. There are a few other nearby places that have smaller populations of these two plants, but Camas Meadows is their primary home.[7]
Endagered Species
The Wenatchee larkspur is confined to a small total range and apparently a very specific set of habitat conditions, located in eastern Washington. Washington's state Department of Natural Resources has suggested that appropriate habitats within the range of this species should continue to be inventoried.
Threats and Management Concerns
Subdivision and subsequent development of rural residences represent a major threat to this species. Hydrologic changes resulting from development and associated road construction also pose a significant threat. Timber harvesting and grazing pose localized threats for some populations.
