Dreams of cottage garden plans are not complete without tall and stately hollyhocks, offering wonderful architectural interest in their height, colors, and bloom shape. Our Hollyhock Roots Chaters Double Mix is composed of fully double, ruffled flowers that come in a range of colors. Making a popular choice for the back of a flower border, or alongside a mid-height fence, Chaters Double Mix offers a profusion of blooms on each stalk, blooming throughout summer.
