Linaria purpurea pops up all over the place at this time of year, a plant of southern Italy that self-seeds readily and is widely naturalised in the UK. Most commonly the flowers are indeed purple and accordingly it goes by the name of Purple Toadflax.
 There is also a less common form with pale pink flowers known as L. purpurea Canon Went. Purple Toadflax is a bee magnet and it looks like the same can be said of the pink variety.
