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: Cercidiphyllum japonicum

Our latest newsletter: Cercidiphyllum japonicum: A tree brimming with elegance; Autumnal Allure; Late Season Sale!

Cercidiphyllum japonicum: A tree brimming with elegance....

An inhabitant of China and Japan, Cercidiphyllum japonicum usually grows as a refined multitrunked tree with a pyramidal to rounded canopy. Cloaking gracefully structured branches, the lovely somewhat heart-shaped deciduous leaves unfurl in bronzy purple tones, and later exhibit medium bluish green hues for summer. The foliar grand finale includes brilliant yellow, apricot, orange or mauve colors plus a sweet strawberry-like scent that wafts some 15 feet or further on sunny, warm fall afternoons. This easy-care tree prefers adequate moisture as well as some protection from hot scorching sun and drying winds.

Autumnal Allure...

One of the greatest joys of gardening is witnessing the changes that occur in our landscapes throughout the year, and many deciduous woody plants pretty much top the list for affording dynamic seasonal transformations, especially in autumn. Most of the trees and shrubs featured in this newsletter are renowned for both their handsome habits and prismatic fall displays. We’ve also included a few of our favorite perennials that lend late season floral or foliar intrigue.

All of us Digging Dog plant wranglers wish you Happy Digging!
