Clematis macropetala was first introduced from China early this century. It is similar to Clematis alpina, which is from Europe, but with a fuller flower.
The typical colour is blue, but there are now forms of white and pink available, although the pink tends towards a shade of mauve.
In Great Britain, C. macropetala grows to between 2.5 and 3 metres. The first flowering period is April to May, but usually a second flowering occurs in July. In the USA and Canada, C. macropetala is said to be hardy in zones 3 - 9.
From my experience it grows just as well out of direct sunlight as in it.
It is also a very suitable clematis for growing in pots. I suggest using a centre pole
of up to 1 metre, and training the plant to cascade down from the top of this pole. A
hanging basket, secured upside down on top of the pole, is ideal for this method of
training. The diagram to the right demonstrates this structure, and the photo above shows
