Blue Star

Amsonia 'Blue Ice' is one of our favourite perennials for edging. The clusters of plump, navy blue buds open to large, vivid periwinkle blue star shaped flowers. The bright green leaves turn yellow in the fall. Amsonia adds a soft, billowing finely textured element to your landscape design. From spring to fall this plant always looks great.

Growing and Maintenance Tips

Amsonia is one of the most forgiving and easy care perennials you can grow. Plant it in full sun to light shade in average well drained soil. Give it too much shade or soil that is overly rich and it can become floppy. Cut the stems back after flowering to keep the plant bushy and neat.
