General Culture:

Easily grown in average, medium, well-drained soil in full sun to part shade. Prefers moist, loamy soils. Good drought tolerance. When grown in too much shade, plants tend to become more open and floppy. Although cutting back most Amsonias to 6-8" after bloom is recommended in order to help maintain neatness and increase foliage density, such trimming is usually not needed in the case of this compact plant.

Noteworthy Characteristics:

A compact, erect, clump-forming plant which features terminal, pyramidal clusters of blue, 3/4", star-like flowers in late spring atop erect, leafy stems growing up to 18" tall. Willow-shaped, green to grayish-green foliage may turn an attractive yellow in fall. Some resemblance in growth habit to garden phlox. The Amsonias are members of the dogbane family and are commonly called blue stars. This plant is sold under several names: Amsonia tabernaemontana 'Montana', Amsonia tabernaemontana var. montana or Amsonia montana. This plant differs from Amsonia tabernaemontana in that the flowers are a deeper blue, the leaves are slightly wider, the habit is more compact and the flowers bloom 1-2 weeks earlier.
