Gravel root

Gravel root (Eupatorium purpureum) is a herbaceous perennial native to eastern and central North America and now New Zealand due to escaping cultivation. Although gravel root isn’t generally considered an ornamental garden plant, it does boast showy clumps of bright, pink florets on tall stems that sport whorls of elongated leaves. In spite of its striking appearance, the fact that the plant attracts rather than deters many kinds of insects may also explain why gardening enthusiasts prefer to admire it in its natural habitat.
