Corydalis

The closest relatives of this striking genus are the bleeding hearts. The Greek name, meaning “crested lark,” alludes to the graceful, birdlike 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 fragrant and richly hued, quick-to-establish Corydalis. These blooms really are the color of blackberry wine, and set against the fernlike, blue-green leaves, give a heady liveliness 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 fine 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 fervor alongside Begonia ‘Alba’ and backed by bold-leafed Rodgersia ‘Bronze Form’.

Blooms May–September

Size: 15" high x 15" wide.

Hardy to zone 4.

<i>Corydalis curviflora var. rosthornii</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 offerings. fine cut blue-green foliage graced with a gossamer-like delicacy showcases these fragrant sapphire-blue flowers. The refreshing cool colors command our attention amid 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.

Corydalis flexuosa ‘Pere David’ (P-0450)

Each $8.25

AVAILABLE FALL 2019

<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.

<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.

<i>Corydalis ochroleuca</i>

Native to rocky woods and naturalized on 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 with green lips and yellow throats add a delicate touch to crevices or walls. For more brightness, we combine this almost year-round bloomer with Campanula ‘Blue Waterfall’ and Brunnera ‘Silver Wings’.

Blooms June–October.

Size: 18" high x 18" wide.

Hardy to zone 5.

Our Featured Plant: Geranium nodosum ‘Clos du Coudray’

Gorgeous Geraniums, Long-lasting summer flowers, Saturday Strolls!

Gorgeous Geraniums!

True Geraniums are sturdy yet refined, with 5-petaled flowers borne on dainty stems above attractive, palmately divided leaves. Their spectrum of colors, from cool to electric, is rivaled only by their ability to create soft mounds and flowing carpets of lush foliage in ordinary garden soil. We plant an assortment of cultivars to always have some in bloom from spring to fall. Our hardy selections are easily grown and most will re-bloom after flowering if lightly trimmed. Be sure to browse our online selections.

Enjoy these blossoms all summer long….

Our newsletter features a diverse collection of long-blooming perennials and shrubs whose reliable flowers will grace your garden for months. These lovely blooms unfurl at the beginning of summer and continue flowering through August or September. Offering unique hues, they populate airy sprays, tall spires, blowsy flower heads or bold verticillasters. We hope you’ll find these long-bloomers as delightful as we do. 

Happy digging and happy summer from all us Digging Dog Plant Wranglers!
