Summary
Blue dogbane (Amsonia tabernaemontana) adds a fine-textured element to the garden with its willow-like foliage, graceful stems, and charming blue star-shaped clusters of flowers during spring. It grows 2-3’ tall and performs well in full sun to partial shade and dry to moist soils. It is a low maintenance, long-lived plant that can be used in informal settings and perennial borders, and it also makes a good cut flower. In the fall, golden–yellow foliage makes blue dogbane an excellent backdrop for other perennials. Blue dogbane is a nice companion with Raydon’s Favorite aromatic aster (Symphyotrichum oblongifolium ‘Raydon’s Favorite’), golden ragwort (Packera aurea), grayhairy wild indigo (Baptisia cinerea), Carolina Moonlight false indigo (Baptisia ‘Carolina Moonlight’), downy phlox (Phlox pilosa), and foxglove beardtongue (Penstemon digitalis). Zones 3-9.
