Jacob's Ladder Characteristics
Jacob's Ladder showy perennials that have good tolerance for heavy shade and cool climates. The soils should not be allowed to dry out. To keep the appearance of the plant looking tidy, cut the flower stalks back to the foliage after the blooming season. If the flower stems are cut back, reblooms are possible. Propagation occurs by self-seeding which can happen easily in optimum conditions.
There are few serious disease or insect issues that threaten the health of Jacob's Ladder. Hot and humid climates may bring leaf spot, powdery mildew, and leaf scorch. Dry soils will result in the tips of the leaves turning brown. Foliage decline is possible in the height of summer.
