Winter Flowering Clematis

Winter Flowering Clematis
We have had this plant for many years with very little flowering to be seen. It was growing in a pot. 2 years ago we moved it to one on the new trough containers I built and it has really thrived. 
This is the first year that it has bloomed in abundance. A real beauty.
