Vernonia lettermannii ‘Iron Butterfly’

Vernonia

Culver's Root

These vigorous American denizens promote an obliging stalwart demeanor plus welcome late summer flower-power. 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’.

<i>Vernonia lettermannii</i> ‘Iron Butterfly’

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 flower color plus triumphs over hot dry conditions as well as sandy, infertile rock-strewn sites.

Blooms August–September

Size: 2' 0" – 3' 0" high x 18" – 2' 0" wide.

Hardy to zone 4.

Our featured plant: Cercidiphyllum japonicum

Our latest newsletter: Cercidiphyllum japonicum: A tree brimming with elegance; Autumnal Allure; Late Season Sale!

Cercidiphyllum japonicum: A tree brimming with elegance....

An inhabitant of China and Japan, Cercidiphyllum japonicum usually grows as a refined multitrunked tree with a pyramidal to rounded canopy. Cloaking gracefully structured branches, the lovely somewhat heart-shaped deciduous leaves unfurl in bronzy purple tones, and later exhibit medium bluish green hues for summer. The foliar grand finale includes brilliant yellow, apricot, orange or mauve colors plus a sweet strawberry-like scent that wafts some 15 feet or further on sunny, warm fall afternoons. This easy-care tree prefers adequate moisture as well as some protection from hot scorching sun and drying winds.

Autumnal Allure...

One of the greatest joys of gardening is witnessing the changes that occur in our landscapes throughout the year, and many deciduous woody plants pretty much top the list for affording dynamic seasonal transformations, especially in autumn. Most of the trees and shrubs featured in this newsletter are renowned for both their handsome habits and prismatic fall displays. We’ve also included a few of our favorite perennials that lend late season floral or foliar intrigue.

All of us Digging Dog plant wranglers wish you Happy Digging!
