Clematis cirrhosa var. purpurascens ‘Freckles’ looks a million dollars at any time of year but in December and January it’s priceless particularly as it has been festooned in delicate clusters of flowers for weeks, with the occasional one showing all through the year. However before you run off to purchase one, and let me say that it would be a good buy, make sure you have a position from where you can look up to admire the flowers. I had to gaze upwards with the camera to take this shot.
I have another winter flowering clematis with a flawed beauty to consider in a few weeks when all the buds burst into flower.
