This perennial plan was in my garden when I moved here in PA 3 yrs ago. It is self seeding, and produces flowers constantly from mid May to mid October. It has leaves that are similar to that of mums and tiny flowers that resemble daisies with a yellow middle and lots of white petals. I was not able to find a picture of this plant on the web nor could my local nurseries identify it. One said it was a form of a mum and another said it was a wild flower. I not so sure about that. Any help with identification will be greatly appreciated. I hope I have posted below the picture of the plant successfully.
I don't think its working-sorry
