- Title: Over The Garden Wall The Rock
- Date: 22nd July 1994
- Summary: The final programme in the series visits the west of Ireland, the Burren in County Clare, south of Galway Bay, which is one of Britain's finest natural rock gardens. This limestone wilderness is buffeted by Atlantic storms, but it is nevertheless home to over six hundred species of flowering plant. The geology and history of the area is explained by Dr Charles Nelson from the National Botanical Gardens, Dublin and local author Maryangela Keane, who discover why plants from as far apart as the Arctic and Mediterranean grow happily together at sea level. The programme also features two designers who have been inspired to create a range of rock gardens: Caiolte Breatnach grows 'Burren Bonsai' in a nursery and in Ballyvaughan Catherine O'Donohue grows potentilla. Finally Charles Nelson visits the gardens at Glasnevin in Dublin where he holds the National Collection of potentilla.
