General Culture:
Easily grown in average, medium, well-drained soil in full sun to part shade. Prefers moist, loamy soils. Tolerates some drought. When grown in full sun, plants often require no pruning or staking. When grown in some shade and/or in rich soils, however, plants tend to become more open and floppy and often require staking or pruning. For a neater appearance, particularly for shade-grown plants, consider cutting back stems by 1/2 to 1/3 after flowering to promote bushy growth and, if desired, a more rounded foliage mound.
Noteworthy Characteristics:
Bluestar is a Missouri native herbaceous perennial which occurs most frequently in rich, open woods and thickets in the southwestern part of the State. An erect, clump-forming plant which features terminal, pyramidal clusters of 3/4", soft light blue, star-like flowers in late spring atop erect, leafy stems growing 2-3' tall. Narrow, willow-shaped, dull green foliage may turn an attractive yellow in fall.
