Perennial erect plant from most of Europe, often found on bog land and wet heath where it avoids lime-rich soils.

Bright blue, trumpet shaped flowers with a green longitudinal stripe along the centre outside of each petal. Leaves are linear - ovate lanceolate and have just one vein upto 2 inches long.

Flowers July-September.

Not the easiest plant to keep happy
