Characteristics:
Prairie smoke is a perennial, often to 30 cm broad, consisting
primarily of basal leaves which are compound-pinnate. The blades are from 5-18
cm long and the numerous leaflets are parted or dissected. The blades are covered
with long, grayish hairs. The flowering stems are reddish and may be up to 40
cm tall, with a pair of reduced leaves at midstem.
The flowers are terminal, with one to nine flowers in a cyme.
The calyx is reddish-purple to pink or yellow in color. The 5 petals are light
yellow, white, pink, or red-purple tinged. When in bloom, the flowers nod or
arch downward. As the fruits mature, the flower becomes erect. The fruits are
elongate, feathery achenes.
Prairie smoke is a great addition to the grassland garden and should be readily available at many native plant nurseries.
Importance:
Native Americans boiled the roots to make a tea. The plant is
an interesting perennial for the rock garden or prairie garden.
Habitat:
Prairie smoke is found in moist sagebrush plains and foothills,
to subalpine ridges and talus slopes.
Range:
Old man's whiskers may be found on the eastern side of the Cascades
from British Columbia south to the Sierra Nevada. It is found eastward to Newfoundland,
and south to New York, Illinois, Nebraska, through the Rockies to New Mexico
and Nevada.
