These vigorous American denizens promote an obliging stalwart demeanor plus welcome late summer flowers. A nectar feast for the butterflies, Vernonia can be peppered throughout meadow plantings and native landscapes, accompanying chums such as Helianthus ‘Lemon Queen’, Eupatorium ‘Riesenschirm’ and Sporobolus ‘Tara’.
AVAILABLE SPRING 2022
We owe a round of applause to Dr. Allen Armitage for his University of Georgia plant trials, which produced this highly acclaimed selection of Arkansas resident, Vernonia lettermannii. Distinguished by dainty-looking thread-like green leaves, the robust, yet compact, attractively branched mounding habit affords small, tubular bright purple blooms housed in showy terminal sprays. Possessing both a herculean mettle and ultrafine texture, ‘Iron Butterfly’ demands free-draining niches, extends seasonal interest with warm rusty-toned autumn flowers plus triumphs over hot dry conditions as well as sandy, infertile rock-strewn sites.
Size: 2' 0" – 3' 0" high x 18" – 2' 0" wide.
Hardy to zone 4.
