Prairie smoke (Geum triflorum) adds interest to a garden bed from early spring through to fall. This perennial is native to North American prairies. It gets its name from the long, wispy, feather-like achenes (seed heads) that develop during the summer. With their pinkish shades, they create an impression of puffs of smoke remaining on the plant for several weeks. The small, pink, bud-like flowers may not be as impressive as the achenes, but they still add a splash of color to the garden in the spring. And during the fall, the foliage takes on purplish, reddish, and orange hues and then turns to a burgundy shade during winter.
