Dahlia 'Plum Surprise' bears dark burgundy red pompom flowers. It's ideal for making a splash of colour in the border or bedding display and also makes a good cut flower.
For best results, grow Dahlia 'Plum Surprise' in full sun in fertile, well-drained soil. Deadhead regularly and feed with a potash-rich fertiliser to prolong flowering. Lift tubers after the first frosts and store them in a cool, dry situation until March. Then pot them up and keep them in a temperate greenhouse before planting out in late May.
