I had heard that Shasta Daisy's were invasive, but then I had also heard them called Ox-Eye Daisy, so I decided to research it a bit when I saw these blooming today. Both the Shasta and Ox-eye Daisy are not native to the U.S.A., but only the Ox-Eye Daisy is considered to be an invasive species. For once, it appears that I actually have the "good kind."
