Another variety, Polemonium caeruleum, grows up to a yard (metre) tall, blossoms in early summer with blue or white flowers, and stays around till autumn. This variety is native to Europe.
The flowers of “False Jacob’s Ladder” can be used as a salad garnish. Both varieties were used in herbal folk medicines.
Cats love both kinds.
