It is a very attractive plant for a border or bed with moist but well-drained soil. The leaves give the plant its name as they are divided like ladder rungs, and the blooms are cup-shaped and white. White Jacob's Ladder plants are native to Europe growing in damp grasslands, woodlands, meadows and rocky areas. Polemonium Caeruleum Jacob's Ladder usually reaches a height of 28 inches, but occasionally will grow taller. Many people believe the Jacob's Ladder herb can be used as a remedy for several common health ailments, and the herb seeds are grown for medicinal use.

How To Grow White Jacob's Ladder: Sow white Jacob's Ladder seeds indoors 6 - 8 weeks before the predicted last frost date or directly outdoors after frost season is over and night time temperatures are warm. Surface sow Jacob's Ladder flower seeds on good seed starting mix, gently pressing seeds into the mix and lightly covering. Moisten the mix and keep it moist until germination begins. Light is required for best germination. When the seedlings are established, prick out each seedling as it becomes large enough to handle and transplant into 3 inch pots. Gradually acclimatize the Jacob's Ladder seedlings to outdoor conditions for 10 - 15 days before planting out into their permanent positions, space 12 - 18 inches apart.
