Vernonia lettermannii ‘Iron Butterfly’

Vernonia

<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 touted tasteful selection of Arkansas resident, Vernonia lettermannii. Distinguished by delicate 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 ultra-fine texture, ‘Iron Butterfly’ demands free draining niches and 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.

Exceptional Echinops, Plants to freshen up your August garden, Saturday Strolls!

Exceptional Echinops!

The striking floral orbs sport either frosty white, cobalt blue or metallic-blue shades, while perched atop sturdy erect stems with handsome jagged-edged foliage. Cherished by pollinators, floral designers and gardeners alike, Echinops thrive in sunny, well-drained niches, though are tolerant of poor soil as well as rock-strewn or sandy sites. These undemanding European natives are perfect candidates for a formal border, cottage garden, meadow-style planting or a cut arrangement. Be sure to check out our online Echinops offerings.

Cool colors for your summer plantings….

Icy white, pale pink and chartruese shades perk up our August borders, while effortlessly blending with just about any color imaginable. These composed hues provide our eyes with bright, yet soothing focal points and an overall beat-the-heat ambience! Some of our cool-down favorites include: Echinops, Sidalcea ‘Elsie Heugh’  Euphorbia mellifera, Kniphofia ‘Green Jade’, Phlox ‘David’ and Tanacetum ‘Isla Gold’. I’ve also featured a handful of richer-toned flowers that I discovered on my early morning walk today. We hope you’ll try sprinkling a few of these perennials amid your landscapes and enjoy both their tranquil or more spirited effects.

Happy August and Happy Digging from all of us Digging Dog plant wranglers!
