Precious purple blossoms with deeper purple centers and a tiny dot of yellow will carpet your garden in a low-growing blanket of color with this perennial. Purple Beauty offers about a month of profuse and slightly fragrant blooms in late spring to early summer beckoning butterflies and hummingbirds to dance amongst her lovely petals. When she's done blooming, her mossy foliage stands on its own as a low-lying textural element in your garden.
