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.

Milling about the mountainous meadows of Europe’s Carpathian Range, this garden rarity spotlights large ruby red thistle-styled blooms bolstered by impressively tall sturdy stems. Even before the marvelous flowers appear, intricately detailed buds with brown-tipped green scales and curvy white spines beg a closer glance. A delicate-looking rosette of long feathery leaves—silver-gray and narrowly cut—completes the picture, while yellow blooming Centaurea ruthenica makes an ideal companion.

Blooms June – August.

Size: 4' 0" high x 2' 0" wide.

Hardy to zone 5.

Exceptional Echinops, Plants to freshen up your August garden, Saturday Strolls!

Exceptional Echinops!

The striking floral orbs sport either frosty white, cobalt blue or metallic-blue shades, while perched atop sturdy erect stems with handsome jagged-edged foliage. Cherished by pollinators, floral designers and gardeners alike, Echinops thrive in sunny, well-drained niches, though are tolerant of poor soil as well as rock-strewn or sandy sites. These undemanding European natives are perfect candidates for a formal border, cottage garden, meadow-style planting or a cut arrangement. Be sure to check out our online Echinops offerings.

Cool colors for your summer plantings….

Icy white, pale pink and chartruese shades perk up our August borders, while effortlessly blending with just about any color imaginable. These composed hues provide our eyes with bright, yet soothing focal points and an overall beat-the-heat ambience! Some of our cool-down favorites include: Echinops, Sidalcea ‘Elsie Heugh’  Euphorbia mellifera, Kniphofia ‘Green Jade’, Phlox ‘David’ and Tanacetum ‘Isla Gold’. I’ve also featured a handful of richer-toned flowers that I discovered on my early morning walk today. We hope you’ll try sprinkling a few of these perennials amid your landscapes and enjoy both their tranquil or more spirited effects.

Happy August and Happy Digging from all of us Digging Dog plant wranglers!
