Polemonium reptans

Polemonium reptans
 
Polemonium reptans, commonly called creeping Jacob's ladder, is a native wildflower that occurs in rich, moist woods and along streams. Typically grows in a mound to 12" tall. Features light blue, bell-shaped flowers in loose, terminal clusters appearing on sprawling, weak stems in mid to late spring. Pinnately compound leaves with oval leaflets are arranged like the rungs of a ladder. Sometimes also commonly called Greek valerian.
 
Care:
Best grown in moist, humusy, well-drained soil in part shade. Tolerates full sun in cool summer climates. Although technically rhizomatous, plants do not creep as the common name somewhat erroneously suggests. Freely self-seeds in optimum growing conditions.
