Description

This native perennial wildflower is 4-10" tall and more or less erect. A small rosette of basal leaves may be produced, but it withers away before the flowers bloom. The margins of these basal leaves, when present, are hairless. Multiple flowering stems are produced that often branch. These stems are light to medium green, 4-angled, and either hairless or slightly hairy along their angled margins. Pairs of opposite leaves occur at intervals along each stem. These leaves are about ½–1" long and less than ¼" across; they are medium green, lanceolate-oblong or linear-lanceolate, smooth or ciliate along their margins, and single-veined. Secondary leafy stems often develop from the axils of the opposite leaves along the primary stem. The upper stems terminate in small flat-headed clusters of flowers. Individual flowers are about ¼" across, consisting of a tubular corolla with 4 spreading lobes and a green calyx with 4 linear-lanceolate teeth. The color of the corolla can vary from pale purplish pink to white; there are conspicuous hairs along its throat. The flowers of Long-Leaved Bluets are dimorphic
