Giant Ironweed
Vernonia gigantean
|
However, hear are some pointers.
Giant Ironweed, 20-30 flowers per flowerhead, smooth leaves
Missouri Ironweed, 35-55 flowers per flowerhead, hairy leaves
Prairie Ironweed, 20-30 flowers per flowerhead, smooth leaves with dark dots on the underside
Keep in mind that these characteristics can be variable, and the plants interbreed. Hmmm.
Flowerheads have 20-30 flowers per inflorescence |
The leaves are less hairy than Missouri Ironweed |
The stem is smooth to slightly hairy |
