Hi Tami!!
I have 7 coming and when I talked to the girl on the phone she saiys that people need to prune no matter what group the first couple years to get it to throw off more shoots.....While I was on the phone, she had me go prune my Sweet Autum Clematis.....

And with my Snow Quenn, it is real short but has 3-4 blooms.....I bought it last year......she told me to prune to the first set of leaves after it is done blooming...Of the ones I have comeing, I got all groupe 3's...the hard prune's.....Hope this helps!!

Oh, and to tell you where to plant, it depends on what you have as some DO take some shade...
Good Luck!!
