Design tip
Summer flowers carry the middle of the season, so place it where the bed needs color once spring bulbs fade. Give it open sun and room to fill out, and repeat it in threes or fives so the planting reads as one sweep instead of scattered dots.
Where to see it
This plant can be seen at the Bellevue Botanical Garden.
