Plumbago

Ceratostigma plumbaginoides

Plant Details:

Plant Type: Perennial
Plant Family: Plumbaginaceae
Plant Description: This spreading, low-growing perennial is incredibly useful as a vigorous ground cover. Shiny, medium-green leaves turn bronze-red in autumn. 5-petaled, sky blue flowers appear in loose clusters from late July to late September, attracting a variety of pollinators. Grows well in sun or shade. Might be best used in a contained area, as it can grow aggressively and overtake less vigorous plants in some situations.

Maintenance:

Maintenance Type: Perennial - Herbaceous
Plant Care: Perennial - Herbaceous (soft-stemmed plants that die back in winter and regrow in spring): Remove spent blooms to promote rebloom later. Some plants tend to flop over after the first bloom and attempt to regrow from the base; in these cases, the old stems can be cut away in summer. As plants become dormant in the fall, remove dead leaves and stems.
Special Considerations: Large patches can simply be mowed down once in late winter, before it begins to regrow in the spring.
