I am trying to identify a perennial in my garden . I bought it a few years ago and have successfully split it. The Leaves are large, shiny and close to the ground. It blooms, tiny mauve flowers, as small as gypsophelia, late in the summer, on thin stick-like growth, about 24″ high, emerging from the centre of the leaves.
What a lovely airy plant you have, which I believe to be Limonium latifolium or Sea Lavender with large sprays of tiny light blue or light purple flowers. Loved by bees and other beneficial insects. To enjoy the dried flowers, cut the spray when fully open and hang upside down in an airy location. Enjoy your handsome plant, whatever the season.
