24-36" x 18-24" wide. Here is a distinctive, new-to-cultivation native perennial that provides both flower color and foliar texture in the garden. Selected as a more compact version of a little known wildflower species from Arkansas, Iron Butterfly is a densely branched perennial with finely textured, almost thread-like foliage and bright violet-purple flowers capping the stems in late summer-early fall. A rich source of natural nectar, the plant is extremely attractive to butterflies.
As soon as your order is placed you will receive a confirmation email. You will receive a second email the day your order ships telling you how it has been sent.

"This is a great plant for massed areas. The bees and butterflies can't stay off them and I would recommend this plant to anyone that wants pollinators!"
"Great selection for ironweed."
"I left a review 1 year ago right after I planted- they did well their first year, but they are so much better now. I cut them down to the ground in early spring and did nothing else to them for the rest of the summer. They came up just as I had hoped and the pollinators love them. I think I will just let the photos speak for themselves."
"I think I ordered the last 2 they had in April. Planted them and they are coming up very well in June. We are having a terrible drought so I was worried. I wish I had known about these earlier, I sure would have put more in my gardens. But as soon as they are available again, I will stock up. I'm putting them along my outer garden facing a road. Looking forward to the color and to being able to offer another late season food source for my garden friends."
"Iron butterfly is a true four-seasons perennial that belongs in almost every perennial garden. In the spring, narrow dark green foliage resembling Amsonia hubrichtii creates a compact shrub-like appearance. The growth is so dense that no weeds have a chance of invading a mature stand of plants. By mid to late summer, gorgeous deep purple fine-textured flowers cover the plant for 4-6 weeks. Butterflies, bees, and other pollinators flock to the occasion. Following the bloom, the flower stocks are sturdy and hold up very well for fall and winter interest. The flowers themselves produce mostly non-viable seed and cling to the plant creating a silvery shine whenever sunlight hits it. This can be very useful and dried flower arrangements as well as winter interest gardens. At some point in the winter, all top growth will need to be cut back as this is the only maintenance required. Despite being native to gravel and sand bars along rivers, Iron butterfly Vernonia surprisingly can handle very dry clay, gravelly, or sandy soils along with short periods of flooding. Permanently wet soil is not favored but it can handle the upper portions of a rain garden. Iron butterfly only has one pest problem and that is rabbits! However, if rabbits are an issue, just put a bowl-shaped chicken wire cage around the plants for the first year. By year number two, the rapidly growing foliage will outgrow any detrimental rabbit browsing. This is definitely one of the most adapted landscape plants in Kansas zone 6a with no problems with heat or cold, dry or wet; it's hard to imagine a perennial garden without this plant!

"Beautiful plant that grows easily in poor soils with little to no care. I've had this plant in my garden for a few years now and I can always rely on it for amazing color! Best part is that it attracts TONS of butterflies in the fall. Its usually a favorite for my monarch population."
