HOW TO GROW

Sowing: Direct sow in late fall, pressing the seed into the surface of the soil. For spring planting, mix the seeds with moist sand and store in the refrigerator for 60 days before planting. Keep the soil lightly moist until germination, which usually occurs within 2-3 weeks.

Growing: Water seedlings until they become established. Mature plants can adapt well to slightly drier soil, though they prefer moist soil. They thrive in wet soil, even tolerating short periods of flooding. This plant attracts bees and butterflies, and readily reseeds itself.

Harvesting: For cut flowers, choose stems with flowers that have just opened. Strip the foliage that will fall below the water level, and place in water immediately.

Seed Saving: After flowering, the plant will produce seed heads containing small clusters of seed with white fluff. Harvest it promptly to avoid loss, since it easily blows away on the wind. Cut the mature seed heads, or shake them into a container to remove the seed material. Clean the seed as well as possible, then store it in a cool, dry place.

This native plant’s common name of “ironweed” refers to its resilient growth, as well as the rusty color that it sometimes develops late in the season. The genus name “Vernonia” honors British botanist William Vernon, who became known for his research of North American plants in the late 17th century. The species name “fasciculata” means “in bundles,” referring to the tightly clustered flowers.
