No longer available this season.
Giant ironweed blooms in the later summer and early fall, adding grace to the very tip-top of the garden. If you do much driving in the country, you’ve seen the tall plants with bright purple aster-like flowers blooming along the roadsides. Plants provide an important late-season source of food for butterflies. Ironweed thrives in full sun and moist soils in zones 5-8. (Vernonia)
