Centaurea

Knapweed

Centaurea’s heritage extends all the way back to ancient Greek mythology when Achilles’s wise teacher, Chiron the Centaur was wounded by one of Hercules’ poisoned arrows and subsequently cured by this herb’s miraculous healing powers.

Equally at home in a present day border or a more naturalized setting, our hardy undemanding selections paint a bright picture inside as well. The long lasting boisterous blooms are celebrated cut flowers, bringing high-spirited accents to both fresh and dried arrangements.

Appreciative of well draining “sweet” soil, the ever amenable Knapweed withstands some drought, but not wet, wintertime feet.

<i>Centaurea hypoleuca</i> ‘John Coutts’

Cradled by silvery, paper-thin bracts, a vivacious summertime showing of deep rose-pink thistlelike blooms with pale centers promises a fall encore when deadheaded regularly.

Long green leaves—deeply divided, lobed and powdery white beneath—line stiff-backed stems, bolstering the fragrant high energy performance.

A magnet for butterflies and gardeners alike, this carefree Centaurea exhibits a compact, not-so-tall profile that can be featured atop a wall or near the border’s front, obliges dry soils and keeps us coming back well after the flowers have faded to relish its long lasting, decorative seed heads.

Blooms July–August.

Size: 2' 0" high x 18" wide.

Hardy to zone 4.

Our Featured Plant: Crocosmia ‘Zeal Tan’

Captivating Crocosmias, Plants that Dodge to Dog Days of Summer, 2020 T-shirst have arrived!

Captivating Crocosmias!

Crocosmias boast a bounty of late summer color as our gardens transition into autumn. Displayed on the ends of gracefully arching spikes above winsome sword-like leaves, the clustered tubular flowers range from yellow, peach and orange to fire-engine red. The prismatic tones meld well with white-flowering Hydrangeas and perennials such as Selinium wallichianum, Actaea simplex 'Atropurpurea', Alcea 'Polarstar' or Aster 'Bridal Veil'. The yellow and melon shades sparkle amid the blue blossoms of Aconitum, Caryopteris 'Longwood Blue', Perovskia 'Blue Steel' and  Aster 'Little Carlow'. For sizzling fun you could create a hot border, intermingling them with Kniphofia 'Bee's Sunset', Helenium 'Potter's Wheel' or Helianthemum 'Fire Dragon'. Be sure to add some to your next cut arrangement!

Commonly known as Montbretia, they do their best when provided with good drainage, moderate moisture and some protection from hot afternoon sun. Please feel free to check out our extensive collection of Crocosmia cultivars in the perennial section of our online catalog.

Dodge the Dog Days of summer….

with plants that pack a punch of blooms and alluring leaves at this time of year. By late August, our borders can look a tad tired and may be in need of some sprucing up. Adequate moisture and an additional application of compost will ensure late summer vitality. You can trim perennials, such as Nepetas and Geraniums, and savor their fresh new growth plus a flourish of blooms, often until the first frost! We hope some of the plants featured in this newsletter lift your spirits and maybe even inspire a little awe as summer wanes. 

All of us Digging Dog plant wranglers wish you Happy Digging and good health.
