This is not the cropland weed (A. syriaca) that farmers curse! Grow this North American native for the sweet scent, the butterflies, bees, and the beautiful mid- to late-season colour. Allow the Monarch butterfly larvae to munch all the leaves they want and watch them pupate over the winter— the plant will return next spring. Easy from seed with winter-sowing. Won't reliably re-seed in one area, since the fluffy seedheads travel long distances in the wind. Extremely hardy, but not the best choice for drought-prone areas.
