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.

Ringed with spidery ultra-fringed tubular florets, the dark-as-midnight blooms are presented singularly, strutting sumptuous reddish purple shades on tall staunch stems. Black embroidered buds, intriguing seed heads and silver felted new growth further enhance the tidy clump of broadly lanceolate green leaves that sport minute pearly hairs. A fan of lean chalky sites, this fanciful bloomer appreciates periodic pruning and works best as a filler in a Mediterranean planting, cottage garden or a naturalized setting, where it will bring on the bees, butterflies and other admirers.

Blooms May–June.

Size: 18" high x 18" – 2' 0" wide.

Hardy to zone 3.

Our featured plant: Euphorbia mellifera

Click here to view our latest newsletter: Exceptional Euphorbias, Notable November Color, Nearly Winter Sale!

Exceptional Euphorbias...

This diverse genus includes approximately 2000 species! Some of our Euphorbias enliven the fall landscape with vibrant red, orange and yellow foliage while others remain evergreen, lending welcome year-round interest. Best of all, many are adorned with acid-green and chartreuse blooms in late winter and early spring, when few other plants are flowering. Appreciative of well-drained soil, Euphorbias are easily grown and their blooms make unique additions to cut arrangements. Be sure to check out our various online offerings!

Notable November Color...

As November comes to an end, a quieter mood prevails in our gardens. Many perennials are either dormant or getting ready for their winter’s rest. Though, some of the more stalwart ones, especially those that are located in protected spots still exhibit a foliar presence and a handful of flowers. The blades and dried buff or silver-hued inflorescences of quite a few ornamental grasses thankfully remain standing, providing movement and delightful rustling sounds. Many deciduous and evergreen shrubs continue to hold our interest either with fall color, artful bark and branching patterns or year-round foliage. The plants featured in this newsletter caught my eye during one of my walks through the nursery and garden this past week. All of us plant wranglers at Digging Dog hope you had a wonderful holiday with family and friends, and perhaps found some time to enjoy your garden.

Happy Digging!
