Ceratostigma plumbaginoides (Dwarf Plumbago)

Ceratostigma plumbaginoides, also known as Dwarf Plumbago, is a low-growing, herbaceous perennial prized for its vibrant blue flowers and striking foliage. This mat-forming plant features wiry stems adorned with shiny, oval green leaves that turn a brilliant bronze-red in the fall. From mid-summer to mid-fall, clusters of gentian blue, five-petaled flowers bloom above the foliage, creating a stunning display. Its ability to spread via rhizomes makes it an excellent choice for ground cover, erosion control, or filling in sunny to partially shaded areas.

Native to western China, Dwarf Plumbago thrives in USDA hardiness zones 5–9. It performs best in full sun to part shade and prefers moderately fertile, moist, well-draining soil. This hardy plant tolerates a wide range of soil types but dislikes wet, poorly drained conditions. With a mature height of 6–12 inches and a spread of 12–18 inches, it is perfect for borders, rock gardens, or underplanting shrubs. Its late-emerging foliage also makes it an excellent companion for spring bulbs, as it hides their fading leaves.

This versatile plant offers year-round interest with its vibrant flowers, colorful fall foliage, and ability to thrive in challenging conditions. It is virtually pest-free, deer-resistant, and low-maintenance, making it a reliable choice for gardeners seeking beauty with minimal effort.
