To many thousands of gardeners, the Chelsea Flower Show is the finest living 'catalogue', full of dazzling colour, fragrance and innovation.
After a particularly hard winter that spectacle would not be possible without months of patient preparation and the years of experience behind each exhibit.
Peter Seabrook meets some of the growers, both on their nurseries and at the showground to find out just what goes into a display worthy of the Royal Horticultural Society's gold medal.
(Coverage of Chelsea Flower Show can be seen on Wednesday at 8.20 pm and heard earlier in the day on Gloria Hunniford's Radio 2 programme at 12.0)
