According to the website of St Andrew’s church, Bothal, Northumberland, the parish war memorial is ‘flanked by a weeping ash [Fraxinus excelsior ‘Pendula’] to the left representing the tears of the bereaved.  On the right the leaves of the Japanese maple [Acer palmatum] turn bright red in autumn symbolising the blood of the fallen.’

Does anyone know of trees being similarly used elsewhere?
