Excluding Sales Tax
Iron Weed is a 5' to 8' tall native perennial often found in heavily grazed, moist lowland pastures, damp alluvial grasslands, and woodland and stream margins. Iron Weed grows best in moist soils and full sun, but will persist in partial shade. This summer and fall flowering plant features large showy 12" wide heads of small brilliant blue to purple flowers. It makes a good contrasting background plant in the garden and is widely used in wildflower meadows, conservation plantings, and wildlife habitat mixes. Bees, butterflies, and other pollinators are strongly attracted to Iron Weed and it is a common component in pollinator conservation seed mixes.
Prices listed are based on pure live seed weight, not bulk weight.
