<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.

<i>Silphium mohrii</i>

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: 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!
