Originally inherited from my Nan, this plant pre-dates the more recent introductions such as ‘Butterfly Blue’ and has certainly proved itself in my garden. Low, slowly spreading clumps of attractive grey-green leaves and lovely soft lavender-blue flowers on short stems over a long period in summer. Easy and long-lived, great in the front of the border or around roses etc. Full sun. 15-30cm H x 30-50cm W. 9cm pot.
