Went on a nature walk in the dunes near Castricum in The Netherlands last week. In one particular small area there were lots of poppies growing. They were not growing anywhere else. The nature guide explained that this was because the soil in this spot had been dumped from other areas and poppies flourish in disturbed soil. Got me thinking about battlefields. All that digging of trenches and the soil being churned up by shellfire. Perfect environment for poppies. Never thought about that before.
