In this week's gardening programme David Maxwell visits the rainforest - but he hasn't gone to the southern hemisphere, he's in south west Ireland at Kells Bay Gardens in County Kerry. The gardens boast a forest of mature Tree Ferns which give them a unique Jurassic feeling. David meets the current custodian of the gardens Billy Alexander who explains how he can push the limits of gardening in Ireland due to the mild microclimate. Also in the programme, Helen Mark visits Conrad McCormick who is growing Cannas and Dahlias from seed.
