I'm currently trying to raise money to secure hosting and other website fees for the next 3 years. If you didn't know, this website is a one-man show and it's a lot of work and money to put together. I want to keep churning out new content and guides and keep everything free, but it would be incredibly helpful and mean a lot if you could make a contribution to keep it going. Even if you can't contribute, sharing posts or the Indiegogo campaign on social media will help make a big impact. Thank you!
Roots and leaves used for food. The roots cooked and added to stews. May taste somewhat like horseradish.
The leaves of the nakedstem wallflower are all basal (most likely why it gets its name). The leaves are slightly toothed with the blade lanceolate or oblong and greyish-green. Stems are 10-30 cm long. Leaves and stems are often covered with silky hairs. The raceme has 3-20 showy flowers with long corolla tubes. The flowers are composed of oblong sepals and four lavender to white purple petals. The anthers are 1.5-2.5 mm in length. Fruits resemble pea pods (similar to those on alpine sweetvetch) and are narrowly oblong with 12-15 ovules per ovary (about 3-4 cm in length).
Distribution and Habitat
Parrya nudicaulis is native to Alaska and Northern Canada, British Columbia, Wyoming and Utah. Six different subspecies can be found in the Russian Far East, Siberia, Central Asia, China, and the Himalayas. I found reference of it being found from Afghanistan to Bhutan at high altitudes.
The nakedstem wallflower or Parry’s wallflower lives in a variety of habitats and soils and can be found in tundra, alpine stream valleys, mountain slopes, gravel, moist meadows, or stony slopes. It seems to favor moist, sandy, or gravelly soils. It typically flowers in early June through early August.
