Jacob's Ladder plants are heavy blooming, produce pendulous clusters of blue or white 1 in., cup-shaped flowers on 1.5-2 ft. stems in late spring and early summer. Flowers attract butterflies and are excellent for cutting.

Jacob's Ladder's lush, fern-like leaves are divided, much like the rungs of a ladder. Plants introduce a tropical appearance to shaded gardens.
