Jacob's Ladder

The Story

Plant Bio

Polemonium reptans, creeping Jacob's ladder, is a low mounding perennial native to eastern North America, reaching one to three feet. Its common name comes from the foliage: neat pinnate leaves with paired leaflets arranged like the rungs of a ladder. Loose terminal clusters of small nodding blue bells open in late spring above the mound.

Despite the name it does not creep aggressively — it forms a slowly widening clump rather than running — so it suits a woodland border where a spreader would be a nuisance. The foliage stays fresh and neat all season if the soil holds moisture, which is more than most spring woodlanders manage.

Uses & Benefits:

Nodding blue bells in late spring above distinctive ladder-like foliage that stays neat all season.

Well-behaved in a border, unlike many woodland spreaders, and long-lived in the right spot.

An important early nectar source for bumblebees emerging in spring.
