Vernonia lettermannii
Ironweed is a deciduous perennial in the Asteraceae family. In summer, showy purple flowers
reach above the needle-like foliage. Preferring moist, well-drained and occasionally dry soil, this plant is drought hardy. Ironweed does well in rocky soil, making it a good choice for a rock
garden. If deer are a problem in your garden, consider this plant as a deer resistant option!
