Dahlia 'Bishop Of York'

Dahlia 'Bishop of York' bears bright yellow single flowers, in contrast with green-purple foliage, throughout the summer. It's ideal for growing in a mixed herbaceous border, and is an excellent late source of nectar for bees and butterflies. It makes an excellent cut flower.

For best results, grow Dahlia 'Bishop of York' in full sun in fertile, well-drained soil. Stake plants early on to protect blooms. 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.
