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.

Spring salutations, early blooms, fresh unfurling foliage!

These early blooming vines and shrubs herald spring!

A choice deciduous shrub for an adequately moist woodland setting, Corylopsis pauciflora offers dangling fragrant primrose-yellow blooms amid graceful branches. The Flowering Current produces long lasting richly colored flowers, bird-friendly berries plus eye-catching autumn color. It thrives in both sun or part shade and handles some drought. 

Easily grown Clematis alpina ‘Constance’ is a small-statured climber that can be showcased in a tight spot or in a patio container. Beloved by gardeners since 1900, Clematis armandii ‘Apple Blossom’ combines lustrous evergreen foliage with copious vanilla-scented blooms, while appreciating a sheltered abode. Both these vines make lovely additions to early spring bouquets.

Spring Salutations!

We’ve been drenched with nearly 60 inches of rain here at the nursery. All that moisture coupled with several warm sunny days, has turned the garden into a verdant wonderland of unfurling shoots, leaves and blossoms. The perennials photographed in this newsletter were taken this week, either in the garden or in our open-sided greenhouses.

Happy Spring and happy digging!
