    Big, long-lasting, semi-cactus flowers top the upright stems for many months from midsummer, creating a dazzling dispaly well into the autumn. Each flower is a sumptuous blend of salmon pink and orange, which merges into yellow towards the centre. The petals are long and thin, and curl backwards on themselves, creating a wonderful spikey effect. Overall they look very impressive, especially when seen against the backdrop of the deep green foliage.

  • 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.
