These clematis are natives of Europe, in particular Southern Europe and the Mediterranean. They are evergreen and grow best against a south facing wall, on a tub on a patio or in a place where there is protection from frost. Also they prefer their roots not to be waterlogged. Height outdoors is generally 3-4 meters.
The flowers are fairly ordinary so the plant should be somewhere where they are visible in winter, either from the house or when entering or leaving. I have found that the cream flowers stand out well at night with a patio light trained on them, enabling me to enjoy clematis flowers when I get home from work on a dark winters evening.
The cirrhosa group is suitable for growing in a conservatory, but may need pruning as given ideal growing conditions they can be quite vigorous, up to about 6 meters. The scent is said to be more noticeable in a conservatory.
In the USA and Canada, C. macropetala is said to be hardy in zones 3 - 9.
It is also very suitable for growing in a pot, in a similar fashion to that of Clematis Macropetala, previously featured on this page. 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 is of a plant trained in this manner.
In the USA the Group is suitable for Hardiness Zones 7-9.
The group is also known as c. calycina.
