What: Ceratostigma plumbaginoides “dwarf plumbago” sparkles in late summer and autumn with sapphire-blue flowers that are increasingly silhouetted against the rich reds and oranges of its fall foliage color. Understated during early summer, it rambles and weaves through other plantings, preparing for its late season surprise.
The spreading perennial late to come up in the spring. Because of this, it makes a great companion for bulbs, often not growing strongly until the bulb foliage starts to die back. It then quickly covers the spent bulb’s leaves.
Where: Place “dwarf plumbago” in full sun or light shade in rich, well-drained soil.
Size: “Dwarf plumbago” grows to 1 foot high by 2 feet wide.
Care: Occasional summer watering encourages a heavier late season bloom. Once the fall color ends, it can be cut to the ground.
