Malva sylvestris Common Mallow
Growing with brighter colours, in a more prostrate form and with many more flowers per stem than I'm used to seeing, this made me wonder at first what species of Mallow it was. The flower shape, fruit and leaf are typical though but perhaps it flourishes like this when conditions are hot and dry.
