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</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.

<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.

Current Staff's Favorite Plant

Helianthus 'Sheila's Sunshine', Persicaria 'Summer Dance', and Selinum wallichianum

Helianthus ‘Sheila’s Sunshine - P-0461

The sunflower was once an emblem of the Sun God of the Incas. Our sunflowers tolerate a wide range of garden soils, attract bees, and make great cut flowers. Blooms early August – October.

Persicaria ‘Summer Dance’ - P-1312

With foliage that’s close to lime-green, and spiky floral tails that approach the scarlet spectrum of rosy pink, this slow spreading perennial is sure to please. Happiest in semishade with ample moisture. Blooms August–November.

Selinum wallichianum - P-1406

This refined Himalayan beauty happens to be one of our favorite perennial umbellifers. With untold elegance, infinitely divided leaves craft a delicate, lacelike transparency. The compact yet airy green canopy is framed by distinctive, purple-infused branching stems that elevate a charming, late season display of white flattened umbels.

Subduing the riotous array of summertime blooms, it seldom needs staking, and appreciates a well draining moist niche. Blooms June–August.
