Peonies. Maybe you’ve never heard of them. Maybe your grandmother grew them. But if you don’t have them in your landscape or flower garden, take another look. They bloom for just a few weeks in spring, but oh, what flowers! Big, round, sumptuous balls of wide petals in so many shades of red, rose, pink and white, with a beguiling sweet fragrance. They rule the garden, and they make wonderful cut flowers, too.
