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.

Sterling plants showcasing white, silver and blue....

Blue is a powerful hue that proffers an air of refinement, sensibility and contemplation, while white and silver gleam with an energized lift. Ivory and blue blooms plus silver-laced leaves add cool sophisticated accents, offering welcome relief on a sweltering afternoon. These colors provide niches where the eye can rest, and when intermingled they create a crisp classic aspect. They can also be threaded through hot-themed plantings for a tone down effect!

Many gardeners are on the look out for plants that can tolerate some dappled light or actually flourish in shady recesses. Chosen either for their commanding foliage or enticing flowers, these diverse offerings promise to enliven just about any low-light garden setting.

Happy Digging!
