Amsonia selections


Amsonia is one of those plants that will make people stop in their tracks and ask what it is. At its peak in mid- to late spring, amsonia is adorned by stunning clusters of powder blue flowers. The show doesn't stop there, however. Its mound of foliage remains attractive all summer long, and as fall approaches, it turns a lovely golden hue. Although the seed pods that develop are attractive, remove them before they mature to prevent self-seeding.

The billowy mounds of 'Walker's Low' or 'Six Hills Giant' catmint produce their first cycle of bloom at the same time as amsonia. Their purplish-blue blooms make a wonderful companion to those of amsonia.


Deep-purple 'Caesar's Brother' Siberian iris creates a lovely foil for amsonia. The grasslike, vertical iris leaves contrast beautifully with the feathery mounds of amsonia foliage.


The pink, blue, or white spires of spike speedwell shine when placed in front of amsonia. The first flush of bloom coincides with that of amsonia, and later cycles use amsonia foliage as a backdrop.
