About Jacob's Ladder
Jacob's ladder (Polemonium caeruleum) is a shade-loving perennial producing ladderlike compound foliage and clusters of blue-purple flowers in spring. In NE Florida's zone 9b, it is best treated as a cool-season annual due to its intolerance of summer heat and humidity. Starting at $19.95.

Care essentials
Light
Grow in part shade to dappled shade, especially protecting from Florida's harsh afternoon sun. Excessive heat and sun causes foliage scorch and rapid summer decline in NE Florida's climate.
Water
Keep soil evenly moist; do not allow soil to dry out. Jacob's ladder is intolerant of drought and will decline quickly in NE Florida's summer heat without consistent moisture.
Soil & Fertilizer
Plant in rich, humus-amended, well-drained soil. In NE Florida, best treated as a cool-season annual or short-lived winter/spring perennial; summer heat and humidity will cause foliage to deteriorate and promote fungal disease.
