 The damage done to the landscape in Flanders during the battle greatly increased the lime content in the surface soil, leaving the poppy as one of the few plants able to grow in the region.Inspired by "In Flanders Fields", American professor Moina Michael resolved at the war's conclusion in 1918 to wear a red poppy year-round to honour the soldiers who had died in the war.She also wrote a poem in response called "We Shall Keep the Faith".
