<i>Silphium integrifolium</i>

Bursting with optimism, this grandiose Midwestern native and Sunflower relative pushes a colony of stout and singular, erect stalks skyward. Coarse textured, rough-hewn lanceolate leaves march up purple-tinged stems, which branch out near their tops to deliver vivacious, 3 in. wide yellow daisies late in the season.

Beloved by songbirds and butterflies, long blooming and undaunted by heavy clay, Silphium integrifolium is undeniably tough and well suited for natural areas or borders alongside tall perennials such as Phlox ‘David’ or Salvia ‘Blue Ensign’.

Blooms August–September.

Size: 4' 0" – 6' 0" high x 2' 0" wide.

Hardy to zone 5.

<i>Silphium laciniatum</i> <i>Silphium laciniatum</i>

Widely distributed throughout our Midwestern tall grass prairies and once considered a life-saver for lost pioneers, this formidable sky-high perennial wields uniquely chiseled, up to 18 in. long basal leaves, which orient themselves on a north-south axis.

Historically crafted into chewing gum by Native Americans, stiff bristly towering stems emit a bitter resin, while large white-haired foliage is cut nearly to the midrib, resembling a Pin Oak leaf. Along the upper reaches of thick stalks, a galaxy of huge, 5 in. wide sunflower-style blooms with yellow rays, yellow centers and hairy-edged green bracts make an exuberant summer long appearance.

Employed as a bold coarse-textured backdrop in cottage gardens, wild flower plantings or mixed borders, its imposing colorful stature lures bees, butterflies and many a gardener.

Blooms July–September.

Size: 5' 0" – 8' 0" high x 18" – 2-1/2' wide.

Hardy to zone 3.

Limited to regions of Alabama, Tennessee and Georgia, this charming American Aster relation asserts a compelling architectural presence. The large, lance-shaped green basal leaves, some 10-15 in. long, sporting fine textured, dense bristly hairs, decrease in size as they ascend strong, branched fuzzy stems. Adored by birds, bees and butterflies, plentiful slightly fragrant clusters gather 2 in. daisy-like pale yellow flowers that afford a long, late season hurrah. Known to be peppered amid Liatris and Baptisia in Pennsylvania’s renowned Chanticleer garden, clumping S. mohrii makes a topnotch addition to perennial borders or naturalized plantings, where it craves a moderately dry rocky spot with low fertility and good drainage.

Blooms July–October

Size: 2' 0" – 5' 0" high x 2' 0" – 3' 0" wide.

Hardy to zone 5.

Our Featured Plant: Geranium nodosum ‘Clos du Coudray’

Gorgeous Geraniums, Long-lasting summer flowers, Saturday Strolls!

Gorgeous Geraniums!

True Geraniums are sturdy yet refined, with 5-petaled flowers borne on dainty stems above attractive, palmately divided leaves. Their spectrum of colors, from cool to electric, is rivaled only by their ability to create soft mounds and flowing carpets of lush foliage in ordinary garden soil. We plant an assortment of cultivars to always have some in bloom from spring to fall. Our hardy selections are easily grown and most will re-bloom after flowering if lightly trimmed. Be sure to browse our online selections.

Enjoy these blossoms all summer long….

Our newsletter features a diverse collection of long-blooming perennials and shrubs whose reliable flowers will grace your garden for months. These lovely blooms unfurl at the beginning of summer and continue flowering through August or September. Offering unique hues, they populate airy sprays, tall spires, blowsy flower heads or bold verticillasters. We hope you’ll find these long-bloomers as delightful as we do. 

Happy digging and happy summer from all us Digging Dog Plant Wranglers!
