Clematis ID please.
Following on from a question a couple of weeks ago I have taken a photo. This clematis has flowered in April for the past 2 years. It's in a pot at the moment. As it's very early flowering I hope somebody may have a clue- if I have some names to consider then 1 may strike a note with me as I usually keep plant labels but can't find this one.

my constance is in flower and looks as like this so it could well be as Bamboo suggests.

Thank you Bamboo and Seaburngirl. I had a look on Taylor's clematis website and it seems the same. I can't remember buying it but seem to remember there was a dead looking clematis in a pot in the garden when we moved in Nov 2013 which put out new shoots in the spring. Good job I didn't bin it! So I now know not to prune it until it reaches the height I want.

Looks like an alpina variety - Clematis alpina 'Constance' maybe?
