Dahlia 'Rothesay Reveller'

Dahlia 'Rothesay Reveller' is a medium-flowered decorative dahlia, bearing purple and white flowers up to 20cm in diameter. Grow it at the back of a mixed herbaceous border, in patio pots or on the cuttings patch - it makes an excellent cut flower.

For best results, grow Dahlia 'Rothesay Reveller' in full sun in fertile, well-drained soil. Stake flowers from June. 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.
