Design tip
Late flowers extend the season, so set it behind or beside plants that finish in midsummer. Because it is easy about light, use it to carry a planting from a sunny end of the bed into the shadier side.
Where to see it
This plant can be seen in the perennial border at the Bellevue Botanical Garden.
