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'–6' high x 2' wide; hardy to zone 5.

Silphium laciniatum  full sun
Compass Plant
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'–8' high x 18"–2-1/2' wide; hardy to zone 3.


Silphium laciniatum (P-1820)

Dainty blooms and unfurling leaves forge an early spring treasure trove of color and texture.

In the last ten days, we’ve experienced all kinds of weather at Digging Dog, including frosty mornings, torrential downpours, deafening hail, glorious sunny 70 º afternoons and even sleet! Thankfully spring is almost here and signs of its arrival grow more evident every day. Brimming with possibility, youthful growth and pristine delicacy, the early spring garden is a fresh treasure trove of color and texture. The plants featured in this newsletter caught my eye while walking through the nursery and along the surrounding borders. Hopefully, a handful of them will spark your interest as well! All of us here at the nursery wish you a very happy spring and countless happy afternoons digging in a garden!
