'Herbert Peabody is a farmer who grows fruit and vegetables in his big, big vegetable patch at Mulberry Tree Farm. When his niece Clementine and nephew Digby come to stay for the school holidays, Herbie can't understand why they know so little about vegetables. But there's a bigger problem: a local bakery is under threat and needs Herbie's help. Can Herbie teach Clementine and Digby the importance of vegetables? And with some hard work and a little bit of magic, can they make something extraordinary happen?"' (Publication summary)
