    Ball dahlias are great because not only do they offer lashings of late summer colour, but their neatly rounded flowers help add structural interest too. Flowering for a long period from July to the first frosts, they are also excellent for cutting.

    In this collection you will receive one of each of the following cultivars:

    Dahlia 'Babette': Sumptuous wine red 'petals', each with a metallic purple sheen, form impressively uniform flowerheads, which are held aloft on tall and sturdy stems. Grows to 1.2m.

    Dahlia 'Sylvia': The bright orange flowerheads provide a vibrant shot of colour - and a fab contrast to rich purples, chartreuse greens and plums. It's a prolific bloomer, particularly if cut for the vase at regular intervals. Grows to 1m.

  • 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.
