| Description |
Life zones and habitat: Plains to subalpine (5000 to 11800 ft.); often moist areas in meadows, open areas in grasslands and woodlands. Plant: Biennial or short-lived perennial 10 to 16 inches tall with weak, slender stem and leafy, prostrate stolons (runners); erect stems produced initially eventually bear flowers followed by sterile runners; fertile stems are leafy only toward the base; leafy sterile stems (stolons) are long, trailing, and often rooting at the tips. Leaves: Alternate, oblanceolate stem leaves, lower leaves on long petioles and up to 1 inch long with entire or dentate margins; smaller upper leaves are sessile, linear to narrowly oblanceolate, and hairy; basal leaves may be persistent (lasting through blooming), broadly oblanceolate to elliptic, 3/4 to 2-1/8 inches long and 1/8 to 3/8-inch wide. Inflorescence: Small, solitary composite flower heads 3/4-inch across with many (40 to 125) white rays, blue- or pink-tinged underneath, yellow disk florets; pointed, hairy and sticky phyllaries. Bloom Period: May to July. References: "Flora of Colorado" by Jennifer Ackerfield, "Guide to Colorado Wildflowers" by G.K. Guennel and SEINet.
