Polemonium reptansAlso known as:
creeping Jacob's ladder,
The blue, bell-shaped flowers of the Greek valerian are borne in loose, terminal clusters atop sprawling, rather weak stems. Oval leaflets are arranged like the rungs of a ladder and give the plant a delicate, fern-like appearance.
Though the genus modifier "reptans" describes this species as a creeper, it is somewhat of a misnomer: this plant has a rhizomatous root system and does not actually "creep". Its native range includes moist, rich, circumneutral soil in humusy woodlands and along streams. Filtered light is best, but Polemonium reptans will tolerate full sun in cooler climates. It will self seed freely under optimum conditions. Bloom times may vary from April to June. Zones 4-7
Propagate from seed or root division after flowering.
This species can survive drought conditions by going dormant. The leaf arrangement of Jacob's ladder gave this plant its common name. It is a reference to Jacob's vision of a ladder to heaven in the Book of Genesis.
