Alkanet flowers come in a range of blues, held above very coarse, hairy leaves.
There are 35 deciduous species, of which only a few are short-lived perennials. They come from dry sunny places in Europe, Western Asia and Africa.
A sunny, free-draining site is best, with little or no disturbance. Deadheading will encourage flowering and removal of the dead flower spike will promote basal growth.
