Ironweed is a tall, deep-rooted, moisture-loving wildflower that can be found near streams and ponds.  It is great for the rear of your pollinator garden or rain garden.  Like many other natives, it can be pruned down before blooming for a shorter plant ('Chelsea chop').  Produces many purple flowers on its tall stalks.  In the Fall, Ironweed generates lots of seed which is a great food source for birds.
