A very pretty perennial useful for the rockery or front of the border with dark green, glaucous foliage, and attractive blue flowers in early summer.
Plant type: Hardy perennial
Flower colour: Blue
Foliage colour: Mid-green
Sun exposure: Full sun, Partial shade
Soil: Well-drained/light, Clay/heavy, Moist

This is a must have. It self seeds everywhere and you can easily replant the seedlings to produce blue/purple colour in abundance. I'm definately going to invest in some of the other colours this spring.
