<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.

Pictured: Preparations for outgoing spring shipments

Digging Dog Nursery is open for website and phone orders, beaucoup thanks to our customers, July flowers!

We're thrilled to announce...

that we are once again accepting phone orders, and by Sunday evening our website will be ready to receive your order. We sincerely appreciate your generous response to our  plant offerings and your admirable patience with us, as we processed an amazing number of orders over the last several months.

Thank you again for your support.

These challenging times have impacted all of our lives….

While 'sheltering in place', many of us have found solace through countless afternoons spent digging in our gardens, spurred on by the prospect of possibility and promise. Perhaps more relevant than ever is what internationally acclaimed garden designer, Mary Keen says. "Gardens are places to be in, not things to look at." Now that's something to strive for!

Here at Digging Dog, our July borders tend to be a happy tumble of flowers and leaves. We've featured some of our all-time favorite perennials in this newsletter. We hope you'll be inspired to dig some of them into your own garden!

We wish you good health and happy digging!

At this time we are so sorry, but we cannot accept on-site nursery shoppers.

Orders may be placed:

Via telephone at (707)937-1130 or 937-1235

or visit http://www.diggingdog.com
