This is a superb and beautiful species forming a large basal cluster of leaves from which arise numerous pyramidal, leafy spikes carrying countless pale blue, saucer-shaped flowers in summer. Each bloom can be 2.5cm (1in) or more across and the effect of a plant in full flower is unforgettable. Although it may last for a few years in the garden, it's best treated as a biennial, raising new plants from seed each year.

excellent plant, performs every year and has done for the past ten. It has become huge now though. Perfect for the back of a bed, also grows in part sun equally as good as full sun
I planted this from seed 3 years ago and because I had no space they spent a year in pots where they did very little. Planted out last summer in a border with full sun and it has just come into flower this year(early August) It looks great is a really bight blue self supporting spires about 1 1/2 - 2 metres tall.
