 How to plant Jacob's Ladder seeds 

Jacob's Ladder plants are heavy blooming. They produce pendulous clusters of blue or white, 1 inch, cup-shaped flowers on 1.5-2 foot 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.
