Overview
Plumbago (Plumbago auriculata), sometimes called skyflower, is a heat-tolerant perennial shrub known for its powder-blue blooms. Native to South Africa, it thrives in the warm, sunny climate of East Texas and is ideal for adding soft color and structure to garden beds, borders, and containers. Its sprawling habit makes it excellent for covering bare spots or trailing over edges.
Light Requirements
Plumbago thrives in full sun, although it will tolerate light afternoon shade. Full sun encourages the most abundant blooms and a compact, bushy shape.
Soil & Planting
This plant adapts well to various soils but prefers well-draining, compost-enriched soil. Space plants about 2–3 feet apart, and mulch around the base to retain moisture and control weeds.
Watering
Water regularly during the establishment phase. Once mature, plumbago is moderately drought-tolerant, though it benefits from consistent moisture during extreme heat. Allow the top inch of soil to dry out between waterings.
Fertilizing
Feed every 4–6 weeks during the growing season with a balanced fertilizer (such as 10-10-10) to encourage bloom production and healthy foliage.
Seasonal Care
In East Texas (zone 8), plumbago may die back in hard winters but will usually return from the roots if mulched well. Cut back to the ground in late winter or early spring to encourage fresh, vigorous growth.
