USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).

Details
36-48" tall x 18-24" wide. A remarkable native perennial, Silver Ironweed is a standout where ever it's planted. The upright stems of long, thin silver-white foliage and late summer display of bright pink, butterfly attracting flowers are unlike any other plant currently in cultivation. Rarely found in cultivation outside of TX, this heat-loving beauty needs limey soils and dry growing conditions. A somewhat slow grower, it seems to establish a deep root system before growing a lot of stems and leaves. Leave standing for winter interest and cut its herbaceous stems to the ground each spring. Thanks to Lauren and Scott Ogden for seed collected near the Davis Mts. of west TX. Plant with Yucca and Agave. (seed/cutting propagated).

Planting Guides
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.
  • Special comments:
  • 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.
