Hardy Plumbago (Ceratostigma plumbaginoides)

Hardy Plumbago, also known as Leadwort, is a tough, low-growing groundcover prized for its vivid blue flowers that appear in late summer and continue into fall. As the season progresses, the plant’s rich green foliage turns a striking bronze-red, providing outstanding fall color. It’s ideal for edging, rock gardens, or underplanting shrubs, and it forms a dense mat that helps suppress weeds. Hardy Plumbago is deer resistant, drought-tolerant once established, and thrives in a variety of soil types.
