Each flower can grow up to 15cm across, so this alone makes them pretty impressive, but the fact that you will never really be sure the exact colouring of each, makes them even more interesting. Some start off as either red or white, but as they mature, their colour changes - the whites to red and the reds to white. Coupled with this, there are some that are simply bicoloured red and white, so the overall effect can really be incredibly colourful.
- 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 over-crowded. 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.
