Design tip
Summer flowers carry the middle of the season, so place it where the bed needs color once spring bulbs fade. 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.
