I agree Alisdair, the flower certainly resembles Alyogyne huegelii. The leaves can be deeply indented, it is a little difficult from the photo to see, but Carole it is beautiful plant to have in your garden and certainly not a weed or pest here in Australia, in fact I would like to see it used more in gardens. There are other flower colours you may like to look out for. violet, blue, white and a rose pink. must have good drainage, likes a sunny position but benefits from wind protection perhaps from other plants, trim back after flowering to keep from getting straggly is also beneficial. Hope it grows really well for you.
