Polemonium reptans is a perennial flowering plant in the Polemoniaceae family, commonly known as Jacob's ladder or Greek valerian. It is native to eastern North America, where it is found in rich woods, meadows, and along streams. The plant is appreciated for its decorative qualities in gardens and its historical use in traditional medicine.

Description

Polemonium reptans grows to a height of 30-50 cm (12-20 inches) with a spread of 30 cm (12 inches). It has pinnate leaves with 5-13 leaflets, each leaflet being 1-5 cm long. The plant is named "Jacob's ladder" due to the arrangement of its leaves, which resemble the rungs of a ladder. In spring, it produces clusters of bell-shaped, blue to lavender flowers, each about 1.5 cm in diameter. The flowers are hermaphroditic, having both male and female organs, and are pollinated by bees.
