This attractive perennial looks wonderful when
covered in flower from early summer. The pale, lavender-blue flowers
perfectly complement the hairy, scalloped and wrinkled, silvery,
blue-green leaves. From afar the flowers appear as a haze of blue.
The plant has greyish leaves which are woolly underneath, and purple flowers in summer. Cats adore the plant, rolling in it and even eating it. Found in the wild in hedgerows, it is a magnet for butterflies, hummingbirds and especially bees.
