Silphium


Silphium integrifolium  full sun
Silphium integrifolium

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.

Silphium laciniatum Silphium laciniatum

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.

Ornamental Grasses: Autumnal Garden Stars, Plant for Outstanding October Oomph!

Celebrated headliners of the late show!

Offering superb versatility, ornamental grasses become poetry in motion on gusty days. They are best situated so their fluid shimmering inflorescences, bathed in amber, sable or smoky rose and purple shades, are backlit and set aglow by the afternoon sunlight. Most look fantastic in fresh or dried arrangements, while others produce welcome seed heads that birds adore. Be sure to browse our online selections of ornamental grasses.
