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.

As Summer draws to a close....

September is a transitory month in the garden. As summer’s end approaches, the shadows are growing longer and the days are becoming shorter. This time of year may find some landscapes a tad lackluster. When designing your garden, you may wish to include plants that remain perky thoughout the season or experience their heyday now. The plants featured in this newsletter provide a lot of late season oomph and promise to beckon you down the pathways of your garden.

Our next guided Saturday Stroll is September 16th., followed by October 7th. We hope you’ll come visit us this summer.
