Dahlia 'Bishop of Oxford'

Position: full sun
Soil: fertile, humus-rich soil
Rate of growth: average
Flowering period: July to September

The soft orange flowers are held above the purple-flushed foliage on dark-coloured stems, creating a lush blend of colour that really stands out in the border. Mix it with rich orange and red, or shades of yellow for a harmonious combination. Alternatively, try it as an accent with plum and purple.
Garden care: Dahlia tubers can be planted outside after frost, or started off in pots under glass in late winter to early spring. Plant them horizontally approximately 12cm deep, making sure the ‘eyes’ are uppermost. Allow enough room between each tuber so the plants can grow and spread to their full size without being overcrowded. While in growth, provide a high-nitrogen liquid feed each week in June, then a high-potash fertiliser each week from July to September. Stake with canes or brushwood if it becomes necessary. In mild areas, leave them in situ over winter, but protect the crown with a generous layer of dry mulch. In colder areas, carefully lift and clean the tubers once the first frosts have blackened the foliage and allow them to dry naturally indoors. Then place the dry tubers in a shallow tray, just covered with slightly moist potting compost, sand or vermiculite and store in a frost-free place until planting out again.
