This really is a superb plant for the edge of a trough or to tumble over walls or a rock in the rock garden. Foliage emerges in early spring from a central point and initially looks very hairy. It extends on wiry stems and takes on a green appearance, each leaf resembling a pine needle, although only 1 cm long. Each stem grows flat to the ground and eventually terminates in a single flower. There are many stems and flowering can last from july until early frosts. Each flower is a strong violet blue and emerges from a black haired bud to around one inch wide with violet hairs at the mouth. Highly recommended.
