wondering which group is this blue clematis

It is blue and supposed to have double flowers earlier in the year and a repeat of single flowers later in the year. It might have had a Japanese name.

It has been in a pot and is probably 12+ years. It has never flowered well and only ever had the double flowers. It gets to 6 feet in height

I've pruned it yearly as a group 3 , down to about a foot in late Jan. Having more free time I'm replanting the garden and thinking to put the clematis against a fence in the garden. Hoping it will do better out of a pot.

I'm wondering if it does poorly because I'm pruning it as the wrong group? 

I don't think a photo helps as there are just browning leaves.

    It's probably a Group 2 if it has two flushes, but you can treat them  as Group 3.
    The more likely reason for it doing badly is because it's in apot, and not getting enough nutrients and water to thrive. The sooner you get it in the ground, the better  :)
    Bury it a little deeper too - and it'll send up more shoots from below ground.

    If you can't plant it in the ground, take pity on it and water it regularly - daily in hot spells - and give it a liquid feed once a week in the growing season and a generous helping of a slow release fertiliser (clematis, rose or tomato) every spring.

    If you can plant it out, cut back half the top growth and make sure it is thoroughly soaked in its pot while you dig a deep hole, bigger than iot's pot and add plenty of well-rotted garden compost and manure to beef up the soil.  Plant it a few inches deeper than it was in its pot and back fill.   Water well.  provide a decent support so you can spread its new stems as horizontally or diagonally as possible so they produce more flowers.

    It also depends where you live, and your growing conditions. Group 2s here rarely do much in the way of second flushes. The odd flower. Season isn't long enough.  :)
    Give it a bit of a chance, and it'll benefit from it anyway  :)

    How kind of you both to respond so quickly as you have done before for me. Very much appreciated. I planted it out this morning as per your advice. Hope I'll be posting a picture of success with it next year
