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.

Our featured plant: Hydrangea quercifolia 'Sikes Dwarf'

Perennials that cool down a hot summer day, refreshing foliage, soothing blooms, last chance to take advantage of our summer sale!

Bring sparkling beauty to your August plantings

Perhaps you’re looking for some soothing floral or foliar accents on a hot summer day! We’ve found that snowy white, clear pink, pale yellow and deep blue blooms coupled with silver, bluish green or emerald-toned leaves become refreshing counterpoints to warmer-hued flowers. They offer a place where your eye can rest, much like cleansing your palette when tasting wine. These shades meld the spicy-colored flowers of many Achillea, Crocosmia, Dahlia, Geum, Helenium, Kniphofia, Rudbeckia and Salvia.

Our next guided Saturday Strolls is August 19th., followed by September 16th & October 7th. We hope you’ll come visit us this summer.
