Prarie Smoke

Geum triflorum is a native North American perennial commonly called Prairie Smoke, for the appearance of the wispy seedheads. Other common names include Old Man’s Whiskers, Purple (or Red) Avens, Long-Plumed Avens, and Three-Flowered Avens. It is widely distributed across southern Canada and the central and northern U.S. in temperate and sub-arctic grasslands, and is hardy in zones 3-7. This prairie and open woodland wildflower in the rose family (Rosaceae) can be locally abundant on upland prairie sites. It is commonly found on shallow and gravelly sites as well as in silty and loamy soils. Unfortunately, it has become rather rare over much of its range, out-competed by naturalized invaders and eliminated by development. Native Americans used this plant for medicinal purposes.


Fertilized flowers are later followed by distinctive silvery-pink fluffy fruits (called achenes) that are equally as decorative as the flowers, if not more so. The styles (parts of the female reproductive organs) greatly elongate in the fruit to form plumes nearly three inches long. After pollination the stems slowly turn upright, so that by the time the tufted fruit appear the feathery heads look like smoke wafting away from the plant – or something like the little “troll” dolls that once were so popular. The seedheads remain on the plant for many weeks until they become golden in color and very dry and are dispersed by the wind. They can be harvested and dried for use in flower arrangements. Pick the entire stem and hang upside down in a warm, dry place until dry.Prairie smoke is not a particularly bright and showy garden ornamental, but the nodding, bud-like flowers and fluffy seedheads add interest in an informal garden. Since it is a relatively small plant, use it as an edging, place it in the front of flower beds, in sunny rock gardens, or other locations where it will not be hidden by other plants. It can be a good companion plant for spring flowering bulbs, filling in the areas when the bulbs die back.

This plant is a good addition to meadows and prairies, although it may get lost among taller plants later in the season. It grows well in combination with other native plants that prefer dry summer conditions, including wild flax (Linum spp.), prairie or grayheaded coneflower (Ratibida pinnata), blazing star (Liatris spicata and other species), sheep fescue (Festuca ovina), blue grama grass (Bouteloua gracilis), little blue stem (Schizachyrium scoparium) and Junegrass (Koeleria macrantha). In natural settings it often grows with upland white and silky aster (Aster ptarmicoides and A. sericeus, respectively), shooting star (Dodecatheon meadia), downy gentian (Gentiana puberulenta), Richardson’s alumroot (Heuchera richardsonii), tall blazing star (Liatris aspera), grooved flax (Linum sulcatum), purple prairie clover (Petalostemum purpureum), downy phlox (Phlox pilosa), rigid aster (Oligoneuron (=Solidago) rigida), and and various native grasses including Dichanthelium (=Panicum) oligosanthes scribnerianum and prairie dropseed (Sporobolus heterolepis).
