Are some dahlias hardier than others?

| On a walk round the garden this morning I noticed that some of my dahlias have been blackened by frost whilst others in very close proximity are still green, though not flowering. The Bish of Llandaff has received the Last Rites, whilst another one, called Jive, is still dancing less than 2 feet away. I planted 2 other Bishops this summer in different locations and they are equally dead, though various other dahlias are still hanging on.
So has anyone else noticed a variation in dahlia hardiness? |

| Yes, there is clearly a difference. I have only just cut down my David Howards in the back garden; I have one in the front which is still flowering (just). But obviously the hardiness issue is important in respect to the survival of the tubers in the ground over the winter. I have no idea whether some cultivars produce hardier tubers than others. Presumably the size of the tuber is also relevant to winter-hardiness? The most important factor is clearly to make sure that they are not planted in a frost pocket (which many of mine are) and not in an area that can get very damp (ditto) and to mulch, mulch, mulch (not yet done - still warm - currently 11 F at 5 am). |

| If the foliage stands up to frost well will the tuber also be hardier? |

| Probably. It could also be where you have it in the garden; or any microclimates that you might have. I notice some of my dahlias tend to be hardier than others. |
