There is a pattern called "Painted Daisies" by Garden Path Designs printed in 2003 that looks like your quilt.
Garden Path Designs, by Nancy Schwalm , adapted from a quilt displayed in Duluth Minnesota.
I saw a quilt made with the daisies set like your in a quilt store in Michigan this summer. I am combining squares from this pattern and from a pattern in "Sugar Sack Quilts".
