Jacob’s ladder, also known as Polemonium caeruleum (var. spelling coeruleum), is a hardy perennial herb of the Polemoniaceae family that includes phlox and gilia.
The upright stems of P. caeruleum rise regally, often to a height of three feet. Wispy leaves alternate, resembling the rungs of a ladder.
The petals of its clustered blossoms are a brilliant blue, a gorgeous example of nature’s rare blue flowers. Bright yellow stamens provide striking contrast.
P. caeruleum is a late spring to early summer bloomer. Like the hosta, it thrives in shade where there is rich, well-drained soil, and makes a great understory plant beneath trees.
Given the opportunity to go to seed, it will naturalize on your property, returning in greater quantity each year.
