Hi, The Smethhursts generously gave me a pot full of Diascia integerrima a couple of years ago. It has stayed in that pot since then, but other things have appeared in it too. One is some sort of onion, but the plant with the purple flowers is something I'm not familiar with. Can anyone help me identify the plant please? Its foliage is greyish and hairy, but you can't see that in this picture for the flowers.
