Lovely 5 lobed sky-blue flowers with yellow centres clustered together in racemes at top of plant.I did not know to take note of the calyx for ID purposes at the time,but when magnifying these photos the calyx seems to have hairs.Did not note the flower size but when comparing it to the other flowers (pink Herb Pobert 13mm,Dark blue Green Alkanet 10mm)it is definately more than 5mm.Petals flat,not saucer shaped.
