The Ceratostigma ‘Plumbago Leadwort’, Ceratostigma plumbaginoides, is a beautiful, fast growing ground cover with dark oval green foliage, turning to dark blue in late summer and early fall. The small blue flowers make this ground cover more unusual than the rest because of its late blooming time. ‘Plumbago’ reaches a height of 10” and a plant spread of 18-24”. It can be somewhat invasive (like most ground covers) and should be kept under control.
‘Plumbago’ needs full sun but can tolerate afternoon shade. For best results, plant in a fertile, moist but well-drained soil. ‘Plumbago’ works great at the front of the perennial border, shrub borders, rock gardens, or as an edging plant. It looks wonderful with Achillea ‘Moonshine’ and Coreopsis ‘Moonbeam’.
