What Does Ironweed Look Like?

Ironweed plants have some truly beautiful and distinguishing characteristics. Among these is a particularly tall and stiff upright habit. They stand erect with tooth-shaped leaves and have small purple flowers gathered in loose bunches. This makes them a favorite cut flower.

Fond of damp locations, this beautiful flower is often seen along the banks of marshes or small bodies of water. Some varieties are even drought tolerant.

Ironweed Varieties

Ironweed (Vernonia noveboracensis) is a member of the Asteraceae family and includes several species such as Vernonia arkansana, V. baldwinii, V. fasciculata, V. gigantea, V. missurica. All of these ironweed varieties have attractive foliage, striking blooms and interesting fall color.

Using Ironweed Plant in the Garden

Ironweed is at home in the garden and is an attractive back-of-the-bed plant that brings elegance and a pop of color to any garden space. Allow plenty of room for these beauties to spread, some like to stretch out as far as 3 feet. If you’re limited in space, cut the stems midsummer about halfway; this will control growth.

Partner this beautiful wildflower with other butterfly magnets such as fennel, sunflowers, milkweed and hollyhock for a stunning display.

Vernonia ironweed  care is not difficult once you find the best location for your plant. Provide organic compost in the spring and a layer of mulch. Water regularly, while the plant is establishing. This will help prevent moisture loss and provide protection. No other special care is required for this lovely and hardy butterfly magnet.
