Jacob’s Ladder is a small, shade plant that grows in compact mounds. When in bloom, the mounds are covered in loose clusters of light blue, bell-shaped flowers. Blooms occur in late spring to early summer and last 2 to 3 weeks. Flowers are visited ... by a range of bees as well as many butterflies and moths. This plant is not drought tolerant and will die back if allowed to dry out, especially if planted in sunny conditions. Its compound leaves and dangling flower clusters offer a unique appearance and texture to the landscape.
