Clematis ID help please????

I planted this clematis last Spring, and I don't recall that it came with a tag. Any ideas for a possible name for this cultivar?

It is pretty. When does it flower?

Thanks, in the Spring. I see clematis with the same color but the leaf shape is different and I'm curious about the name.

I am wondering if it is a Niobe..... http://www.clematis.hull.ac.uk/new-clemdetail.cfm?dbkey=27

I was initally thinking that your clem looked a lot like Madame Julia Corravon, which is why I asked what time of year yours flowered. Madame Julia flowers in the summer.

Attached is my Madame Julia, there are some definite similiarities. Your thoughts?

Carolyn22, nice pic of Madame Julia. My blooms have 6 petals and it looks like MJ has 4-5 petals per bloom? Similar color however. I've grown Niobe in the past. This bloom is larger. Wish I had better picture. I'll have to post a better one when it blooms this year. Thanks for helping. Annette
