Rose (Rosaceae)

Three-flowered Avens

Geum triflorum Pursh

This unusual plant is recognized by the long, pink, feathery hairs that catch the wind and help scatter the fruit. Unlike many other perennials, its basal leaves stay green all winter. The flowers remain partly closed, and are pollinated by insects, mainly bumblebees, with enough strength to force their way in. Because they bloom in early spring, Three-flowered Avens provide an important energy source to insects coming out of hibernation.

Canadian Rarity Status:

Physical Appearance:

The pinkish stems of this plant grow to 40 cm tall. Basal leaves occur in a low rosette, and are each divided into 7-19 toothed leaflets. The stem leaves are smaller, and also toothed. Flowers occur in threes, nodding from long, hairy stalks. They stay mostly closed, and have five petals hidden behind dark pink sepals. Dark pink, hairy bracts extend from the sepals. After blooming, each flower straightens up and produces numerous achenes with long, pink, feathery hairs.
