That's what the lady who lived here before us called. I'd like to know what it really is. the stems and leaves are quite sticky and look like a succulent. It seeds like crazy, and has these clusters of five petalled almost magenta flowers.
Thank you, ladies. I thought perhaps that's what it was. I am very happy to let it stray around the garden to it's heart's content, and if it gets in the way, it's easy enough to move. perhaps I should save some seeds. . .
