Gardening magazine. The Malvern Spring Show heralds the start of the flower show season. The Gardeners' World team are there highlighting the best plants in the floral marquee and finding the latest in design ideas from the show gardens.

2010 is the Malvern Show's 25th anniversary. It's also the International Year of Biodiversity. Combining those two factors, Toby Buckland, Carol Klein and Joe Swift are keen to find out how the way we garden has changed over the last quarter century and how nurturing wildlife has become second nature to gardeners.

Toby seeks out growers as they set up their floral displays and finds plants which not only look gorgeous in our gardens but also provide precious food for beneficial insects, moths and bees.

Carol explores the diverse and extended rose family - she identifies its cultivated cousins on display at the show and then goes in search of its wilder relatives out in the hedgerows.

Joe looks at how today's designers are using more sustainable materials in their show gardens and also finds inspiring planting combinations that will increase the biodiversity of all our gardens.

And Alys Fowler is spending time at a nursery prior to the show to find out how they get their plants up to the medal-winning standard expected for floral exhibitors.
