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’.

A robust presence, unsurpassed late fall color and a compelling winter silhouette are this North American prairie dweller’s claim to fame. Painted with opulent crimson-purple hues, the flat branched heads of Aster-like flowers surmount proud stiff stems and long lance-shaped, rough-to-the touch green leaves. A finale of fluffy white seed heads matures to a rusty orange, earning its common name, while the genus pays tribute to William Vernon, a British botanist who collected the species in Maryland in 1698.

Clump-forming Ironweed is well-suited for a modern meadow-style theme, holding its own amongst bold, green bladed Miscanthus or more airy Molinia or tall perennials like Helianthus ‘Lemon Queen’ and Aconitum. Beloved by bees and butterflies everywhere, it’s easily cultivated, appreciating a well drained moderately moist site.

Blooms August – September.

Size: 5' 0" high x 12" – 2' 0" wide.

Hardy to zone 5.

<i>Vernonia fasciculata</i> <i>Vernonia fasciculata</i>

Venerated for its iron-related traits including arrow-straight brawny stems, fluffy warm rust-tinged seed heads and a rugged constitution, this easily grown late bloomer roams the moist prairies from Ohio to North Dakota and south to Missouri, Oklahoma and Texas. Glabrous green linear leaves line smooth stalks, rendering a brilliant purple burst of densely clustered composite flowers that hosts the American Painted Lady butterfly. Its substantial hard-working presence can be featured in informal borders or meadow-style settings and ensconced with Sanguisorba 'Chocolate Tip', Eryngium yuccifolium and native grasses.

Blooms July–September

Size: 2' 0" – 4' 0" high x 18" – 3' 0" wide.

Zone 3/4.

<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.

A flashy new 2014 Jelitto Seeds introduction, this quibble-free white-blooming version of the New York Ironweed propels erect upright stalks, densely cloaked in serrated, lanceolate green leaves, buoying fluffy delicate plumes of narrow-petaled creamy white daisies. Followed by decorative seed heads, the long-lasting late season blooms make bright additions to cut arrangements and entice many garden visitors, especially the bees and butterflies. "White Lightenings" clumping bushy habit can be massed or planted as a striking focal point for a somewhat informal venue, where it readily adapts to variable conditions.

Blooms August–October

Size: 6' 0" high x 2-1/2' wide.

Hardy to zone 4.

Our featured plant: Euphorbia mellifera

Click here to view our latest newsletter: Exceptional Euphorbias, Notable November Color, Nearly Winter Sale!

Exceptional Euphorbias...

This diverse genus includes approximately 2000 species! Some of our Euphorbias enliven the fall landscape with vibrant red, orange and yellow foliage while others remain evergreen, lending welcome year-round interest. Best of all, many are adorned with acid-green and chartreuse blooms in late winter and early spring, when few other plants are flowering. Appreciative of well-drained soil, Euphorbias are easily grown and their blooms make unique additions to cut arrangements. Be sure to check out our various online offerings!

Notable November Color...

As November comes to an end, a quieter mood prevails in our gardens. Many perennials are either dormant or getting ready for their winter’s rest. Though, some of the more stalwart ones, especially those that are located in protected spots still exhibit a foliar presence and a handful of flowers. The blades and dried buff or silver-hued inflorescences of quite a few ornamental grasses thankfully remain standing, providing movement and delightful rustling sounds. Many deciduous and evergreen shrubs continue to hold our interest either with fall color, artful bark and branching patterns or year-round foliage. The plants featured in this newsletter caught my eye during one of my walks through the nursery and garden this past week. All of us plant wranglers at Digging Dog hope you had a wonderful holiday with family and friends, and perhaps found some time to enjoy your garden.

Happy Digging!
