    Nursery contributed plant descriptions

    The deep, warm, radiant yellow of this Dykes Medal winner continues to astonish gardeners nearly 70 years after it was first introduced by Jacob Sass of Nebraska. Its beards are orange, its tall stalks never topple, and it multiplies vigorously. In short, as its Greek name declares, it's "all good."
