Corydalis

The closest relatives of this striking genus are the bleeding hearts. The Greek name, meaning “crested lark,” alludes to the elegant bird-like appearance of the flowers, which grow in ra­cemes among ferny foliage.

<i>Corydalis</i> ‘Blackberry Wine’

Drink in the multitudes of pendulous, white-flecked flowers adorning this sweetly perfumed and richly hued, quick-to-establish Corydalis. The blooms really are the color of blackberry wine, and set against fern-like blue-green leaves, impart a heady aspect to the garden, especially when contrasted with the golden blades of Hakonechloa ‘All Gold’.

Blooms May–November

Size: 10" high x 18" wide.

Hardy to zone 5.

Exalted for its taller, more robust and long-flowering visage, this exciting new Corydalis flexuosa and Corydalis elata cross was bred in France and recently introduced in England. Embodying the best qualities of both parents, ‘Blue Line’s vigorous finely cut foundation maintains a reliable summer presence, highlighting a honey-scented flood of white-throated, deep metallic-blue blossoms on tall reddish-tinted stems. The eye-catching flowers keep coming from spring ’til fall and create quite a show alongside Begonia ‘Alba’ and flanked by bold-leafed Rodgersia ‘Braunlaub’.

Blooms May–September

Size: 15" high x 15" wide.

Hardy to zone 4.

<i>Corydalis curviflora</i> var. <i>rosthornii</i> ‘Blue Heron’

Keenly selected on a collecting trip to Sichuan, China by Dan Hinkley, ‘Blue Heron’ heralds the largest, darkest, richly blue blooms of all our Corydalis offerings. Finely divided blue-green foliage becomes a gossamer-like backdrop for the fragrant sapphire-blue flowers, whose extraordinary cool colors can be enjoyed near fellow shade dweller Epimedium ‘Frohnleiten’.

Blooms April–June

Size: 9" high x 12" wide.

Hardy to zone 6.

<i>Corydalis flexuosa</i> ‘Blue Panda’

Long after other Corydalis have gone dormant for the summer, ‘Blue Panda’ will brighten your garden with vibrant, electric blue blooms above a tidy mound of filigree textured foliage. Tuck it under the upright, vigorous stems of Euphorbia x robbiae and the white flowering Viburnum ‘Chiquita’ for a striking vignette.

Blooms May–November.

Size: 10" high x 18" wide.

Hardy to zone 4.

<i>Corydalis flexuosa</i> ‘China Blue’

Imagine the bluest sky you have ever seen and you may come close to envisioning the flower color of this dazzling and vigorous cultivar. The glaucous leaves provide a lovely backdrop for the carefree clusters of spectacular blue flowers.

Blooms March–July

Size: 10" high x 18" wide.

Hardy to zone 4.

<i>Corydalis flexuosa</i> ‘Pere David’

Perhaps the most vigorous of the flexuosa, this graceful Corydalis spreads by underground stems, forming good-sized colonies of neat, low-mounding foliage adorned with bright blue flowers on willowy stems.

Blooms February–July

Size: 6" – 8" high x 18" wide.

Hardy to zone 4.

We have Hillier Nursery, a venerated UK mainstay, to thank for this valiant, repeat blooming Corydalis. Selected from a group of flexuosa seedlings, it hosts dazzling, large tubular flowers saturated with vibrant frosty-blue shades atop distinctive, fine-hewn, blue-green foliage that dons bronze tones. ‘Porcelain Blue’ provides additional enticements: the somewhat loosely arranged, easy-care clump doesn’t undergo a summer dormancy, plus its show-stopping sweet smelling racemes appear in spring and again in late summer, enchanting bees, hummingbirds and plant connoisseurs alike.

Blooms April–June & September

Size: 12" high x 18" wide.

Hardy to zone 5.

<i>Corydalis flexuosa</i> ‘Purple Leaf’

With an intriguing royal purple hue infusing each leaf, this low clumping species is the earliest blooming Corydalis we offer, bearing smoky periwinkle-blue flowers throughout the winter in our garden. The lovely leaf color holds best in partial shade.

Blooms November–May.

Size: 10" high x 18" wide.

Hardy to zone 4.

Corydalis ochroleuca (P-0387)

Each $8.25

AVAILABLE SPRING 2022

<i>Corydalis ochroleuca</i>

Native to rocky woods and naturalized upon old walls in Europe, this is one of the most beautiful foil plants for a shady garden. The lacy bluish green foliage and creamy-white flowers, enhanced by green lips and yellow throats, add a delicate touch to crevices or steps. For more splendor, we combine this almost year-round bloomer with Campanula ‘Blue Waterfall’ and Brunnera ‘Hadspen Cream’.

Blooms June–October

Size: 18" high x 18" wide.

Hardy to zone 5.

Our featured plant: Eupatorium purpureum

Statuesque Eupatoriums, Aster All-Stars, Late Summer Shipping!

Beloved by bees and butterflies...

Eupatorium, commonly called Joe-Pye Weed, is an easily grown, dignified North American denizen. Its large, hazy-looking broad domes of clustered rosy purple flowers crown sturdy, straight-up wine-tinted stems with textural deep green leaves that are presented in loosely spaced whorls. Lending handsome mass to meadow plantings and either the middle or back of the border, they can also be grouped or planted singularly along pond and stream edges, as well as woodland peripheries. Joe-Pye Weed appreciates sun or bright shade, good air circulation plus fertile adequately moist soil. Favored by bees and butterflies and perfect for cut arrangements, its fluffy blooms later broadcast mulled cocoa shades then morph into attractive seed heads, which nourish finches and tits. Eupatorium ‘Gateway’ struts a bushier more compact stature, while the straight species boasts a mighty sky-bound stance.

Aster’s cheerful daisy faces....

plus the profusion of colors and sizes that make up this genus promise lots of flower power when other perennials have tuckered out. Invaluable for summer and fall gardens, our no-fuss Aster offerings are tried-and-true performers in sunny locales with average soil and moderate moisture. Cherished by plant aficionados, flower arrangers, song birds and pollinators, many Aster cultivars work well in either formal or informal venues and can be tucked into stylized meadows, cottage gardens and borders Please feel free to peruse our additional on-line Aster selections. 

Sprinkled amidst the Asters, we’ve included Hydrangea ‘Limelight’s conical creamy white trusses, the mesmerizing fine-textured foliage of Sorbaria ‘Sem’ plus a handful of other perennials that add late summer appeal.   

 All of us plant and paper wranglers wish you good health and happy digging!
