Ceratostigma plumbaginoides - Hardy blue-flowered leadwortCeratostigma plumbaginoides, commonly called leadwort, is a low-growing, mat-forming perennial native to eastern China. It provides a vivid splash of late-season colour with its bright blue flowers and striking red-purple autumn foliage.
This ground cover plant reaches up to 50 cm in both height and spread. From late summer through early autumn, it produces clusters of intense blue flowers. The oval leaves turn vibrant shades of red and purple as the season progresses. Ideal for rockeries, container planting, or filling gaps in walls and paving.
Hardy down to approximately -10°C, Ceratostigma plumbaginoides prefers a sunny, sheltered location with moist but well-drained soil. Its spreading habit makes it well suited to containers or confined areas where growth can be controlled.
Highlights:
- Brilliant blue flowers in late summer and early autumn
- Striking autumn leaf colour
- Excellent for containers, edging, or ground cover
Points to consider:
- May spread aggressively if left unchecked
- Avoid heavy shade and overly wet soils
This reliable perennial adds colour when most plants are fading, making it a valuable choice for extending the garden’s season of interest.
