Clematis 'Tubulosa'

I don't think i've seen this one Kathy is it a ground cover one ?

More like a perennial really Amy grows to around 4ft with huge leaves and these pretty almost bluebell like flowers which are quite small, dies back completely in the winter,has spread a bit but not a huge amount.

Thanks Kathy , thats interesting !

Very unusual.....lovely

Is it frost proof?

Thanks Motinot:-)
Yes Lulu been planted here around 5 years now, if it can survive last winter it can survive anything :-)must actually google and see if you split it like you do a perennial and whens the best time if you do, would like some in another area of the garden.
