Polemonium

Jacob’s Ladder

Hallmarked by clear true-blue hues, a delectable fragrance and deep yellow centers, plentiful large silky flowers are clustered atop sturdy upright stems. A compact and ferny deep green basal mound of long, finely cut alternate leaflets anchors the beautiful sterile blooms that will not reseed. ‘Northern Lights’s low, tidy mildew resistant habit prefers a bright, evenly moist, well-drained abode, detests hot humid weather and appreciates a judicious dividing each spring to ensure its longevity.

Blooms April–May.

Size: 12" – 16" high x 12" wide.

Hardy to zone 4.

Named after King Polemon of Pontus, this genus is distinguished by fernlike foliage with nearly 20 neatly arranged leaflets, believed in Roman times to symbolize the ladder that spanned heaven and earth in Jacob’s dream.

Asserting a dark mystique, this recently introduced Polemonium cultivar is heralded for the reddish purple and bronze tones of its lush leaves. Deep-hued stems frame the lacy upright base, which transmutes a green flush when summer arrives or when grown in deep shade, and appreciates a somewhat cool, moist setting. Large silken blooms—loosely clustered, cup-shaped and plentiful—compose a violet grace note.

Blooms June–July.

Size: 2' 0" high x 15" wide.

Hardy to zone 5.

Our Featured Plant: Crocosmia ‘Zeal Tan’

Captivating Crocosmias, Plants that Dodge to Dog Days of Summer, 2020 T-shirst have arrived!

Captivating Crocosmias!

Crocosmias boast a bounty of late summer color as our gardens transition into autumn. Displayed on the ends of gracefully arching spikes above winsome sword-like leaves, the clustered tubular flowers range from yellow, peach and orange to fire-engine red. The prismatic tones meld well with white-flowering Hydrangeas and perennials such as Selinium wallichianum, Actaea simplex 'Atropurpurea', Alcea 'Polarstar' or Aster 'Bridal Veil'. The yellow and melon shades sparkle amid the blue blossoms of Aconitum, Caryopteris 'Longwood Blue', Perovskia 'Blue Steel' and  Aster 'Little Carlow'. For sizzling fun you could create a hot border, intermingling them with Kniphofia 'Bee's Sunset', Helenium 'Potter's Wheel' or Helianthemum 'Fire Dragon'. Be sure to add some to your next cut arrangement!

Commonly known as Montbretia, they do their best when provided with good drainage, moderate moisture and some protection from hot afternoon sun. Please feel free to check out our extensive collection of Crocosmia cultivars in the perennial section of our online catalog.

Dodge the Dog Days of summer….

with plants that pack a punch of blooms and alluring leaves at this time of year. By late August, our borders can look a tad tired and may be in need of some sprucing up. Adequate moisture and an additional application of compost will ensure late summer vitality. You can trim perennials, such as Nepetas and Geraniums, and savor their fresh new growth plus a flourish of blooms, often until the first frost! We hope some of the plants featured in this newsletter lift your spirits and maybe even inspire a little awe as summer wanes. 

All of us Digging Dog plant wranglers wish you Happy Digging and good health.
