At first I wasn`t able to descry much difference at all between this one and the ordinary "Jackmanii" (which is I dare say Norwegian gardeners` first choice of clematis.) May be with the exception of a slight touch of wine red. By and by i have learnt to see the special qualities of the Superba variety. The somewhat bigger flowers have a strikingly beautiful velvety and sort of more intense deep violet blue colour with the aforesaid slight touch of wine red. I have two plants, and one of them has been a bit touched by the withering disease which doesn`t seem to affect the ordinary Jackmanii. However both plants are doing very well and one of them has been flowering way into October (check uploaded photos) I do recommend this variety as well.
