Vernonia fasciculata Prairie Ironweed



Vernonia fasciculata produces bristly, upright stems that supports gorgeous, fluffy cluster of violet and purple flowers. Also known as ‘Ironweed”, its foliage resembles a bushy mound of narrow, coarse leaves from mid-summer to early fall and is sure to stand out with its slender appearance.

Vernonia fasciculata Ironweed grows best in full sun or partial shade with moist to medium soil but can tolerate occasional flooding as well as dry soil and clay soil.

Native to the Eastern United States, Vernonia fasciculata is self-seeding and can spread unless deadheaded.

Its taller statue and eye-catching purple flower make fasciculata attractive to pollinators such as butterflies, bees, and songbirds, while remaining deer resistant.

    We ship via UPS or USPS (the Post Office), and their ship rates are automatically generated through our site. We do not profit on shipping costs. We are working with these providers to get our customers the best rates possible.

    All ship times are subject to change if extreme weather conditions are present here at the nursery or at the shipping destination.

    Please note: Depending on the time of year, the foliage of the plants may be trimmed to fit into our shipping boxes. This could delay the flowering of the plant, but many perennials actually benefit from being cut back.

    We are currently not able to ship to Puerto Rico, Hawaii, and outside of the US.
