Forage & honey flows
The Chiltern beech hangers produce an unusual honeydew flow some years; lime, field maple and sweet chestnut are the more reliable June flows through Marlow, High Wycombe, Amersham and Chalfont. In the Vale, oilseed rape dominates the spring and field beans support early June. Bramble is dense on the commons; rosebay willowherb fills every beech-clearing on the scarp. A strong late ivy flow runs across the flint-walled villages and ancient churchyards of the scarp foot.
