Shasta Daisies (Leucanthemum) are the same plants known by many under the genus Chrysanthemum, but as longtime gardeners, we've become used to having plant names change. What hasn't changed is the plants themselves, which are some of the showiest and most reliable perennials for the summer garden. At peak bloom, they produce a mass of daisies so clean and bright they compete in brilliance with the sun. All they require is good, rich soil and lots of sun. When you want Daisies, this is where to look.
