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: Viburnum plicatum var. tomentosum ‘Shasta’

Vivacious Viburnums, Revel in Late Season Repose, Go-Green 2021 Holiday Sale!

Vivacious Viburnums……

Endemic to both Asia and North America, this vast group of graceful cold-hardy shrubs includes more than 150 species and numerous cultivars that are moderate to fast-growing. Our reliable Viburnum offerings sprout dashing deciduous or evergreen foliage with an array of leaf shapes and textures. Their gorgeous flowers unfurl in either a lace-cap style or dome shape, with  species such as V. carlesii and V. x burkwoodii wafting a delectable scent. Many don lustrous bird-friendly fruit, ranging from red to dark purple to black, while others blaze with autumn color. Preferring sun or part shade, these undemanding shrubs can be ensconced in large containers and shrubby borders, or featured as a stellar specimen, clipped into an  informal dense hedge or planted in a drift.

Revel in Late Season Repose……

As November draws to a close, a quieter mood prevails in our gardens. Many perennials are either dormant or getting ready for their winter’s rest. Though, some of the more stalwart ones, especially those that are located in protected spots still present a foliar aspect plus a handful of blooms. The blades and dried buff or silver-laced inflorescences of quite a few ornamental grasses thankfully remain standing, providing movement and delightful rustling sounds. Many deciduous and evergreen shrubs and trees continue to hold our interest either with fall color, artful bark and branching patterns or year-round foliage. The plants that we chose for this newsletter captured my attention, as I was strolling with my trusty canine cohort, Boobah this past week.

All of us plant wranglers at Digging Dog hope you have a wonderful holiday with family and friends, and perhaps find some time to enjoy your garden.
