Yes - in terms of robustness, they fall into three classes:

1) The large-flowered 'Jackmannii' hybrids and similar.
2) The moderately large-flowered garden varieties of other
types, some borderline hardy species and so on.
3) Almost all hardy species and small-flowered hybrids.

In category (3), you can include C. tangutica (orientalis),
C. alpina, C. vitalba, C. x jouiniana (I think) and so on. Most
of them are as tough as old boots, given even half reasonable
conditions (e.g. not solid clay).
