Jacob's Ladder

Polemonium reptans
Polemoniaceae

Growth Habit

Herbaceous

Propagation

Seed Treatment and Storage: cool/moist stratify

Biocultural Value

The Meskwaki used a decoction containing Jacob's ladder root as a powerful cathartic and diuretic.

Wildlife Value

Pollen is transferred onto the heads and thoraxes of both small and large bees when they visit to feed on the flowers’ nectar, although large bees are more effective pollinators because they are more likely to come in contact with the pollen-laden anthers. Though this flower is often visited by syrphid flies (Toxomerus spp.) and fire-colored beetles (Pedilus lugubris), these species are ineffective pollinators because they eat rather than transfer pollen and often visit flowers of a completely different species afterwards.
