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.

Our featured plant: Achillea 'Hella Glashoff'

Amazing Achilleas, Invigorate your summer plantings!

Amazing Achilleas…. These sturdy, dependable perennials produce small indivdual blooms that populate broad, flat flower heads, lending welcome horizontal elements to any garden bed. Ideal for bouquets, fresh or dried, the long-lasting blossoms range in color from alabaster to soft yellow and gold, as well as terracotta, pink and sassy red. Cut back their flowers in midsummer and enjoy a fall encore! Spicy scented, attractive fern-like green or gray-tinged foliage cloaks their strong straight stems. Slowly spreading and somewhat drought tolerant, Yarrow seem to thrive on neglect. They can handle low soil fertility plus coastal wind and salt spray. Be sure to check out our diverse on-line Achillea selections!

Invigorate your summer plantings.… A few simple maintenance techniques will help plants appear fresh throughout the upcoming dog days of summer. The addition of a chipped bark mulch or well-rotted compost, applied as a top-dressing, not only reduces water requirements, but generally makes it easier for plants to maintain perky looking leaves and vigorous habits. A July or early August trimming of long-blooming perennials, such as Nepetas and most Geraniums ensures myriad flowers that will keep on coming ‘til the first frost. Featured in this newsletter, you’ll find the fabulous plants that caught my eye as Boobah and I took our morning walk through the nursery and adjacent display borders this past week. Hopefully, you’ll have room to ensconce several of them in a well-traveled spot. Happy Digging!
