Vernonia noveboracensis

New York Ironweed

USDA Zone: 4-9

Plant number: 1.539.100

In a sunny, moist site Ironweed will form a bold, impressive clump of dark green leaves, with large clusters of magenta-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 are easily divided in early spring. Attractive to butterflies.
