One of the first (and best) summer events in London is the Chelsea Flower Show. As well as the garden competition, growers introduce completely new varieties of plants which are judged by the Flower Show judges. Our favourite from the shortlist for Plant of the Year was the new peony, All that Jazz , which has creamy-apricot petals flecked with dark red and a dark red centre. The winner was a sedum shrub, Atlantis Nonsitnal, which has yellow variegated leaves and small flowers in the summer.
