These are taken in my front yard flower bed. I had planted it 20 years ago when I moved into the house. It blooms every year since then, late spring to early summer. The flowers are the size of a loonie. I didn't take much attention to it until this year, when I am mostly confined at home. Ashamed that I don't even remember the name as the packet with its name on was thrown long time ago. Kindly ID please. Thanks in advance.
