Great plant. No bog needed.
Sky-blue flowers bloom June-frost on 3-4′ stems and sway in the summer breeze. Hummingbirds just love it, and occasionally you can spot a goldfinch on the stems eating the seed. It’s quite the acrobatic show! Looks great at the back of the border, as well as intermingling with other perennials and grasses. Available late April 2019
Full-part sun. All soil types. Spread 3-6′. Zones 6-9.
