DescriptionThis introduced perennial wildflower is 1–2½' tall, sending up one or more unbranched stems from the base. Depending on environmental conditions, these flowering stems are more or less erect, or they can sprawl across the ground. The stems are gray-green or gray-blue, terete, and hairless. Arranged around each stem, there are dense pseudo-whorls of small leaves. These leaves are are up to 1½" long and less than ¼" across; they are linear-oblong, gray-green or gray-blue, smooth along their margins, and hairless. Each stem terminates in a cyme of about 10 flowers. While the flowers are in the bud stage, the slender branches of the cyme usually droop downward. When a flower blooms, it becomes more erect. Individual flowers are about ¾–1" across, consisting of 5 light to medium blue petals, 5 dull green sepals, 5 stamens with white anthers, and 5 slender styles. The petals are much larger than the sepals; they have dark blue veins that radiate from the center of the flower. Individual sepals are ovate with membranous hairless margins. The blooming period usually occurs during early to mid-summer. The short-lived flowers up open during the early morning and close by noon. After the blooming period, each flower is replaced by a globoid seed capsule. Each capsule contains 10 cells (5 fertile cells and 5 sterile cells) and 10 flattened seeds. The root system consists of a deep taproot. This wildflower reproduces by reseeding itself.
