'On the wide level acres of the valley the topsoil lay deep and fertile. It required only a rich winter of rain to make it break forth in grass and flowers. The spring flowers in a wet year were unbelievable. The whole valley floor, and the foothills too, would be carpeted with lupins. Once a woman told me that coloured flowers would seem more bright if you added a few white flowers to give the colour definition. Every petal of blue lupin is edged with white, so that a field of lupins is more blue than you can imagine.'
John Steinbeck, East of Eden
