One of my favorite Clematis, brightens up the early spring days. It has been in flower about 3 weeks here this year the flower is particularly good.
The brilliant white flowers give off quite a strong scent not unlike hawthorn.
It is evergreen and is a little tender so prefers a sheltered wall.
I have it growing up against the wall scrambling through a Ceanothus 'Concha'
It requires little care other than to remove and dead stems after flowering.
I must say it was a relief to see it after the winter this year, I recorded -12c on one occasion.
