Bugbane is built for cool, rich, consistently moist shade — woodland borders, the north side of the house, rain-garden edges — where its dark foliage and fragrant fall spires shine and deer leave it alone. Not a fit for hot, dry, sunny ground: it scorches and wilts where the soil dries out, so give it shade and steady moisture.
