About Plumbago
Cape plumbago (Plumbago auriculata) is a fast-growing, sprawling evergreen shrub from South Africa, prized in Northeast Florida for its nearly year-round display of sky-blue flowers. Drought-tolerant, heat-loving, and butterfly-friendly, it excels as a flowering hedge, bank cover, or cascading accent; prune hard in late winter to keep it tidy and flowering abundantly. Starting at $9.95.

Care essentials
Light
Plant in full sun for maximum flowering; tolerates partial shade but blooms significantly less in reduced light. Full sun is strongly preferred for Northeast Florida's year-round growing conditions.
Water
Drought-tolerant once established; water regularly during the first season to establish roots. Reduce irrigation for established plants — overwatering is a common cause of decline. Prune hard in late winter (March) to rejuvenate and promote vigorous flowering.
Soil & Fertilizer
Grows in any well-drained soil; tolerates poor, sandy soils common in Northeast Florida. Apply a slow-release balanced fertilizer in spring; avoid high-phosphorus blends. May experience micronutrient yellowing in high-pH soils — adjust with sulfur if needed.
