This is a creeping plant with small grey leaves and spiny flowerheads measuring about 150mm. across. These have tiny yellow, four-petalled flowers interspersed with long crimson spines. The nearest I have found is Salad Burnet but that has tufts of red stamens, not spines, and is taller with much bigger leaves. Any suggestions please?
