CERATOSTIGMA plumbagnoides (Hardy Plumbago) Hardy Plumbago is one of the most versatile groundcovers for cold climates growing in both sun and shade and most soil types. Plumbago blooms in late summer with deep blue flowers followed by the foliage that turns burgundy red in fall. The foliage should be cut back in spring, rather than fall, for better overwintering.
A Northern Sunset perennial, it prefers average, well-drained to dry soil in part shade to part sun.
