This Spring I discovered this flowering plant growing in my garden. Mother nature must have blown the seed in or came in with fresh garden soil. I don't know what it is, but I really enjoyed the flowers that lasted until mid summer. It is growing in semi shade with some full sun for a few morning hours. I would love to know what this is and is it an annual, perennial. If it's a perennial, I want to keep it, but need to move it so it doesn't get crowded out next Spring. Thanks!
