Silphium

Silphium laciniatum full sun

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.

Our fall arrangement includes: Asters Hydrangeas Miscanthus Molinias Persicarias Salvias Verbenas

I wanted this arrangement to celebrate the diverse beauty that autumn affords. It was photographed by acclaimed garden photographer, Saxon Holt, who happened to be visiting us.

Autumnal Fanfare: Lambent Leaves, Glistening Berries, Fleeting Flowers, last chance for Fantastic Fall Sale, Gift Certificates now on sale!

Here at Digging Dog, we’ve had some welcome rain to actually soak the soil. With the onset of shorter days and chilly nights, a quieter contemplative mood envelopes parts of the garden. As many herbaceous plants are fading into dormancy, evergreen shrubs, bold-toned leaves, textural seed-heads plus plump glistening berries take center stage. The impressive group of plants featured in this newsletter caught my eye when I strolled through the nursery and garden yesterday. I hope you enjoy these compelling autumnal offerings. In many locales throughout the country, there’s still time to tuck some botanical gems into an empty garden nook.
