The dahlias in this 'Bishop' collection all have luscious, dark coloured foliage, so they are not just sought after for their summer flowers. It is the combination of these two factors however that really makes them stand out. They create a dramatic impact in the border and the flowers, which are excellent for cutting, will also help encourage bees and other pollinating insects into the garden.

In each collection you will receive 1 of each of the following:

Dahlia 'Bishop of Dover': A single row of white ray florets, which usually have a pinkish violet flush, surround the central disc forming pretty flowerheads that are held on deep purple-brown stems. The purple-tinted foliage offers a wonderful contrast.
Dahlia 'Bishop of Llandaff': Striking, semi-double, bright vermilion red flowers appear from July to September above the deeply divided, dark bronze-red leaves. This popular, peony-flowered dahlia requires a sunny site with fertile, humus-rich soil. Perfect for a planting scheme based on 'hot' colours.
Dahlia 'Bishop of York': Cheerful yellow flowers, contrasting beautifully with the purple-flushed foliage, appear for several months from midsummer. Ideal for creating late colour in the garden.

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.
