WHAT: Dwarf plumbago sparkles in late summer and autumn gardens.
Its sapphire-blue flowers begin to appear in August and continue well into October. In the later weeks of its blooming period, its brilliant blue flowers are silhouetted against the rich reds and oranges of the its fall foliage.
WHY PLANT IT: Understated during early summer, this perennial, also known as ceratostigma plumbaginoides, rambles and weaves through other plantings, preparing for its late-season surprise.
It makes a great companion for bulbs, often not growing strongly until bulb foliage starts to die back.
WHERE: Plant it in bright, full sun or light shade in moderately fertile, well-drained soil.
Heavy clay soils should be lightened with sand or compost to improve drainage. It does not tolerate excessive moisture, especially in clay soils in winter. It is a tough plant, tolerating considerable drought once established.
HOW: It is not a dense groundcover and is at its best when mixed with other perennials or groundcovers to extend its season of interest.
Its weaving, spreading habit makes it a good candidate for a rockery, except with very delicate alpine plants. Its bright flowers and fall colors combine well with the tan seed heads and fine textures of ornamental grasses.
Once its fall color ends, stalks can be cut to the ground.
ACTUAL SIZE: It rarely grows more than 15 inches tall and spreads about 18 inches a year.
