    Nursery contributed plant descriptions

    Very interesting perennial with unique fuzzy brown flowerheads with a pink center. While not spectacular in terms of showiness, we think it spectacularly interesting but then we are certifiable plant loons, Sunny spot in poor or good soil that drains. Pretty easy.
