Garden writer Alys Fowler and designers Ann-Marie Powell and Andy Sturgeon join Monty Don, Joe Swift and Rachel de Thame at this year's RHS Hampton Court Palace Flower Show. The event has a countryside theme and so Andy Sturgeon looks at the best cottage garden plants on offer, while Ann-Marie is on the trail of must-have flowers for scent. Monty and Joe also take a look at the show gardens inspired by the Great British countryside, while Rachel discovers what makes 2013's Rose of the Year a winner.
