Late summer and early autumn is go time for pollinators: give them a big boost with 'Iron Butterfly' vernonia (ver-NO-nee-uh). Also known as ironweed, this native perennial looks a bit like a New England aster at first glance, but each flower is an exuberant little puff of pink. The foliage is narrow, with a slightly spiky, willow-like look, and is more disease resistant than most asters, too. Butterflies love this plant, and thanks to its August-September bloom time, sustains them in that crucial period before they wind down for the season.

Iron Butterfly Ironweed

I love the plant, it arrived very successfully and I planted it a day later after fishing it in water.

I have deer and am concerned that they might have tried eating the tops of a couple of the plants!

Is this a deer-resistant plant! I have somewhat if a fence around my plants, just concerned that a deer got in!?!

Thank you,

Lauren M.

Don’t know yet

Since I just planted the Ironweed a month ago or so and we’ve had so much rain, it’s hard to tell. I will let you know next Spring.
