Summary

Olsynium douglasii var. douglasii, commonly known as Douglas’ Grasswidow, is a perennial herb that is deciduous or semi-deciduous. It is native to grasslands, meadows, and open woodlands in the Pacific Northwest of the United States and Vancouver Island in Canada. This plant typically reaches a height and width of 0.4-1 feet (0.1-0.3 meters), forming clumps of grass-like foliage. Douglas’ Grasswidow blooms in early spring, producing striking purple to reddish-purple flowers that are quite showy and attract early-season pollinators.

Douglas’ Grasswidow is valued for its early spring flowers, which can add a splash of color to rock gardens, borders, and native plant gardens. It is relatively low-maintenance, requiring medium amounts of water and thriving in part shade. It prefers well-drained soils and can tolerate a range of soil types, from sandy to loamy. While not commonly used, it has potential in cultivation for naturalized areas or as a component of a mixed perennial border. It is not known for significant disease or pest issues, but it can be sensitive to overwatering or poor drainage.CC BY-SA 4.0
