About plant names...

Prairie smoke, so named for its seed heads’ resemblance to puffs of pink smoke, is a North American native. It is a member of the rose family.

Identification: Plants are 6-18" (15-45 cm) high × 18" (45 cm) wide. Most of the leaves on this plant are near the base. They are small, hairy, and deeply lobed. Flowers are dark red, bell-shaped, hanging downward, in groups of three, ½-¾" (1.3-1.9 cm) each in size. It is the seed heads that are especially unique in appearance, consisting of red or purplish threads surrounded by soft feathery hairs.
