Vernonia lindheimeri (Woolly Ironweed) is a showy perennial that thrives where conditions are tough. This resilient plant can handle low fertility soil, dry climates, and resists deer and rabbits. Woolly Ironweed has a gentle upright habit, sturdy stems, and fine fuzzy foliage with an airy texture. Silvery buds open to clusters of bright magenta disc flowers in mid-to-late summer. Blooming for 6 weeks or more, the flowers nourish native bees and other pollinators. A North American native perennial from Texas and Northern Mexico, its common name comes from its iron-like qualities – both durability and seed clusters the color of rust.
Vernonia lindheimeri (Woolly Ironweed) is a showy herbaceous perennial that gets its name from the fuzzy white undersides of its narrow leaves, giving it a natural defense against deer and rabbits. Woolly Ironweed is native to the sunny hillsides and meadows of northern Mexico and Texas. Plant Ironweed in a sunny location in low fertility soil with good drainage. Water as needed to establish, thereafter it is a waterwise, resilient perennial. Over time, it will naturalize gently, but it is not aggressive. Excellent choice for a rock or alpine garden or xeriscape. Plant with Muhlenbergia rigens Undaunted, Solidago, Aster, and Helianthus for a full palette of fall flowers. It also makes lovely cut flowers. Hardy in zones 7-10, leave it standing over winter and cut back to the ground in spring after new growth emerges.

Vernonia (Ironweed) is big genus of New World wildflowers, with most species native to North America. Members of the Aster family, they are important late season sources of nectar for butterflies.
Preferred growing conditions:
Plant in most soil types including clay.
Best positioned in a full sun to partial shade locations.
Mulch with common mulch materials in dry Western climates. Leave un-mulched in moister Eastern climates.
Water regularly the first growing season to establish the plant. Most species and varieties like moderately moist to wet soils and should receive regular irrigation in arid climates. Rainfall is generally sufficient in moist Eastern climates.
Vernonia lindheimeri v. leucophylla is xeric and should be only given occasional deep watering when conditions are dry.
Deadhead the flowers when blooming is finished. Many species from the Midwest and Eastern US will re-seed aggressively in moist soils. Deadheading is helpful to reduce volunteer seedlings.
Fertilize lightly in the fall with Yum Yum Mix.
Leave standing of the winter and cut back hard in early to mid-spring.
Tall species may need staking unless stem tips are pinched back in late spring/early summer to thicken up the plant's stem structure.
