This is perennial which I grew some years ago from seeds gathered from my mum's garden -- part of the fun of gardening !! It flowers freely for many months in the summer-
@busylady@hillymay Thank you both for your comments , Hillary I do love gather & growing from my own seeds, splitting plants ,taking cuttings --making gardening so much more fun & gives great satisfaction (and cheaper !!!! )
Thank you all so much for your kind comments
