Anemonastrum richardsonii
Also called Yellow Anemone, Yellow Thimbleweed
Richardson's anemone (yellow thimbleweed) is a small perennial wildflower of cold northern regions, named after naturalist Sir John Richardson, with small yellow flowers in early summer. It is not a common garden plant, and it needs cool, moist, well-drained conditions to thrive.
Anemonastrum richardsonii, commonly known as yellow thimbleweed, is named after a Scottish naturalist, Sir John Richardson (1787–1865) who found it on Franklin's expedition to the Arctic. It is a perennial, deciduous plant that blooms in mid to early June.
Anemonastrum richardsonii prefers subarctic climates and can be found in willow thickets, snow patches, along streams, near peat and mosses, and in moist areas with low drainage. It is capable of growing under a wide range of soil pH.
Herbalists use the plant to soothe abrasions, toothaches, rheumatism, and depression. Traditionally, the roots were boiled and used in an attempt to treat paralysis, though this was ineffective. The smoke from the cotton of the ripe seeds was also burned and inhaled to relieve headaches.
