Monty Don, Joe Swift, Rachel de Thame, Alys Fowler and designer Ann-Marie Powell continue their tour of the RHS Hampton Court Palace Flower Show. Monty and Ann-Marie take a look at this year's conceptual show gardens, which defy conventional garden design in favour of spreading their own personal messages. Rachel looks at the Festival of Roses - which, this year, is dedicated to the flower's long associations with romance. Meanwhile, Alys and Joe visit a new category of Summer Gardens with ideas on how to add style to our outdoor spaces. Show less
