Dahlia Bishop of Oxford

Dark foliage and brilliant flowers

The Bishop series of dahlias have glossy purple or bronze tinted leaves that show off the flowers beautifully. This variety has strong stems which carry vivid peachy-orange, single flowers that look as striking in a vase as in the garden. Bees just love this dahlia.

Where?

A sun lover which looks great in a bed, mixed border or large container.

How?

Happiest in rich, fertile well-drained soil and give plenty of water and regular feeding through the summer. Enrich the soil with organic matter before planting - homemade garden compost or well rotted manure is fine. Use a good quality potting compost for container growing. This tall variety should be staked using bamboo canes for support.

Dahlias grow from a storage organ called a tuber. In mild regions they may be left in the ground year round and generously mulched in autumn. Otherwise lift before the frosts and store in a cool, dry, dark place until spring.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
