This doesn't look like the photos in the database!

Oooh ..no it doesn't look like Westerplatte.
It may be Clematis Nelly Moser.

Really the name doesn't matter...as I assume you bought it because you liked it.
Would you have been tempted to buy Westerplatte.

Thank you, SSurfer!
I am new to Clematis and actually own a Nelly Moser:



But, as you can see, mine is much lighter in color. So I was confused by the ones in the store which looked similar, but much brighter, and we're tagged differently. Especially by the bloom of the mistagged one which mine NEVER looked like at all:

Sure looks a lot like Clematis 'Nelly Moser' to me too!

I know almost nothing about Clematis varieties so take this with a grain of salt.

It looks like a tag in the background of your photo says, "- of Style."

If that happened to be "Queen of Style" then that is a HGTV trademarked name for this variety.

Perhaps, someone mixed up the tags?
