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