Characteristics:

1. Basal leaves pinnately divided, parsley-like with long stalks. The stem leaves are smaller and not stalked.

2. Stalks are covered with long, soft whitish hairs. Each stem bears a single flower, and the plants may attain a height of 60 cm.

3. Flowers are large and showy, to 6 cm across. Petals are absent, but the 5 sepals are white or sometimes purplish, and surround a cluster of numerous yellow stamens and a central cluster of small, green pistils. Mountain Pasqueflower blooms soon after the snow melts, which is early summer.

4. Fruits are clusters of single, plumed achenes. The plumes are feathery in appearance, and may be 5-6 cm long. The plumes aid wind dispersal of the seeds. See the photo below.

5. I am not aware of anyone using this wildflower as a rock garden/ alpine meadow plant, nor am I sure how easy it is to propagate and transplant, but it is a gorgeous mountain wildflower, and its plumed seed heads are of added interest!


Habitat:

Mountain pasqueflower is found in mountain meadows near treeline.


Range:

Mountain pasqueflower is found from southern British Columbia south through the Washington Cascades to Oregon, and into the Olympic Mts.
