Vernonia Noveboracensis (New York Ironweed) In a sunny, moist site Ironweed will form a bold, impressive clump of dark green leaves, with large clusters of purple flowers in late summer and fall. A native wildflower of eastern North America, adapting extremely well to border conditions without becoming weedy in the least. Flowers are excellent for cutting. Plants sometimes need to be staked to prevent flopping. Clumps can be divided in early spring. Attractive to butterflies. 1 gal
