Overview

Comprehensive Description

Comments

This unassuming little plant is a good candidate for a rock garden, in either sunny or partial shaded areas. It is easily overlooked in the wild, but when found in bloom is always a pleasant surprise. Lance-Leaved Bluets can be distinguished from other bluets by the wideness of its leaves – up to ¾" across. Other species of bluets in Illinois have narrow to very narrow leaves. An exception is Houstonia purpurea (Wide-Leaved Bluets), which has leaves up to 1" long, sometimes with 3 conspicuous veins. This latter species occurs primarily in woodland areas in extreme southern Illinois. Lance-Leaved Bluets is sometimes considered a variety of this species

Description

This native perennial plant is about 1' tall, branching occasionally and rather bushy when mature. There are scattered hairs along the stems, and the opposite leaves are ciliate, but without serration. The leaves are oblong-lanceolate, broadly lanceolate, or ovate. Each leaf is about 1-2" long and about one-third as wide, with a prominent central vein and a smooth texture. At the ends of the stems are clusters of small flowers. These flowers are usually white or light purple, but sometimes a darker shade of purple. Each flower is about ¼" across, with a short tubular shape and four lobes that flare outward. The reproductive parts are white, except for the light brown anthers. The flowers bloom during late spring or early summer for about a month. There is no floral scent. The small seeds are distributed to some extent by the wind. The root system consists of a branching taproot.
