How do we use your location?
Knowing your location helps us recommend plants that will thrive in your climate, based on your Growing Zone.
6-8 feet tall and 3-6 feet wide, Giant Ironweed (Vernonia gigantea) can provide fall fireworks in the garden or can be pruned back in mid-summer to result in a more manageable maximum height. It’s most effective for pollinator benefit and garden color when planted in multiples of three or more plants. Site plants in full sun in moist soil. Giant ironweed can tolerate wet feet for extended periods of time. They will self-sow, so deadhead when flowers fade to keep the garden tidy. Relatively easy to grow, and not prone to pest and disease problems. Pairs well with other prairie wildflowers and grasses.
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. Some perennials are shipped as potted plants, some as perennial roots packed in peat. The ‘Plant Information’ section describes how that item will ship. All perennials and fall-planted bulbs are packaged to withstand shipping and are fully-guaranteed. Please open upon receipt and follow the instructions included.
Perennials and fall-planted bulbs are shipped at the proper planting time for your Growing Zone. Perennial and fall-planted bulb orders will arrive separately from seeds. If your order requires more than one shipment and all items are shipping to the same address, there is no additional shipping charge. See our shipping information page for approximate ship dates and more detailed information. If you have any questions, please call Customer Service at (802) 227-7200 or contact us by email or chat.
