This comparative lack of trees offers good wildflower displays and wide views. Serpentine soils are found within the Wenatchee Mountains, modifying the plant communities in those areas. The Wenatchee Mountains are home to a number of rare, endemic, or disjunct plant species, including Androsace nivalis var. dentata, Claytonia megarhiza var. nivalis, Delphinium viridescens, Lewisiopsis tweedyi, Trifolium thompsonii, and Valeriana columbiana. The Wenatchee Mountains checkermallow (Sidalcea oregano var. calva) occurs only along Peshastin Creek, south of Leavenworth, Washington. It is the rarest plant in Washington, and is now on the endangered species list.
