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.

“A border flower of the highest merit,” is how British horticulturist, William Robinson once described this awe-inspiring Centaurea, and we couldn’t agree more! Crowning long straight green stems, the fluffy thistle-style heads in unique pale citron yellows and tissue-thin buff-colored bracts will attract more than a few admirers. These ample-sized, sublime-for-cutting blooms heighten a graceful ferny pedestal of rich green pointed leaves with gray undersides, narrow silhouettes and a refined countenance. Appreciative of adequately draining soil, the ever amenable Knapweed withstands some drought, but not wet winter feet.

Blooms July–September.

Size: 3' 0"–4' 0" high x 2' 0" wide; hardy to zone 5.

As Summer draws to a close....

September is a transitory month in the garden. As summer’s end approaches, the shadows are growing longer and the days are becoming shorter. This time of year may find some landscapes a tad lackluster. When designing your garden, you may wish to include plants that remain perky thoughout the season or experience their heyday now. The plants featured in this newsletter provide a lot of late season oomph and promise to beckon you down the pathways of your garden.

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

Customer Comment:

“I just visited Digging Dog Nursery over the weekend, and was very impressed, both by their plants and their beautifully landscaped surroundings. They have a wide range of plants (many which you don't see elsewhere) and everything was healthy, vigorous and picture perfect. The word which comes to mind is "cherished." I bought a few of these beauties and they are blooming already!”
