Salisbury described how new plants--such as gallant-soldier, Oxford ragwort and rosebay willowherb, nicknamed 'bombweed' by Londoners--had flourished in wartime, having drifted in from Europe or America as seeds on food aid or soldiers' clothes, or sprung to life after being buried under bricks and concrete smashed in air raids.
