Are you aware of the Clematis on the Web website? It's an amazing resource when you're looking for this kind of information. You can search for white clematis that's pruning group 3 and then look up the answers they give you to see photos of most of them. A lot of them aren't ones I've seen for sale, but I've always found what I was looking for if I started with the name of a clematis in commerce now. Good luck and have fun.

I can't think of any that fit all your requirements, but there are several that almost do, having white along with another color: 'Venosa Violacea' has purple veining, 'Fond Memories' has a purple picotee edge, and 'Best Wishes' has purple speckles down the center of each tepal. All have a significant amount of white in them and so might give you the effect you want.

There are several on this site

C. alba luxurians has gorgeous nodding-bell flowers, edged in green. It's one of my favorites, but may not meet your requirements. What about the old stand-by, Henryi? Or, to name others I have (or had): C. lanuginosa candida, Marie Boisselot, Hyde Hall, Mrs. George Jackman.

Thank you garystpaul. What is the diameter of the C. alba luxurians flower when in bloom? That actually does meet my requirements as far as pruning group goes (looking for group 3) but I'd like to know the size of the flower. The others you mentioned are beautiful, but they are all pruning group 2. I have a Henryi in another location and love it. I don't want to mix a pruning group 2 clem with the bunch of pruning group 3 clems I'm attempting to establish on one side of a pergola. Thanks! Bill

Clematis on the Web gives C. alba luxurians as being 3". Below I've linked the search engine. If you type in a name, just using one word in the name works best. I found C. alba luxurians using just alba.

I also used it to look for clematis with your requirements, and found that there really aren't many other than what's been mentioned here.

3" is about what my flowers are; a very profuse bloomer, by the way.

Thank you so very much nhbabs and garystpaul! alba luxurians it is!! It fits all my bills having the 3" flower. And thanks nhbabs for the 'one word search' advice on 'clematis on the web' site. I searched there, but used lots of words and luxurians didn't come up. One other that did was viticella 'Peveril Pristine'. It too is 3", is by Barry Fretwell, but does not seem to be available in the US, at least not this year. Thank you again. I've added alba luxurians to my 'to get soon' list! :-)

Sorry to be posting an album of my Clems.

The only pure white I have is Marie Boiselott ~ an absolute beauty. Snow Queen has a hint of lavender.

Another white I have not pictured, is Sweet Autumn.

However Marie is grp #2 tho.

I just found one more clem in my garden that pretty much fits your requirements, Forever Friends. The blossom size range is 2 1/2 to 3 1/2 inches, so it might be a tad small, depending on your conditions, but it's white and type 3. I found it at Brushwood last year.

Ditas, thanks for posting your pics. Really nice collection you've got there. I, too, am a big fan of Marie Boisselot, also Snow Queen.

This one is a group 3, not totally white, more of a pale blue/almost white. I love it. Blue Angel.

Thnx Gary ~ my collection wasn't as pretty this season due to our record drought that lasted 'til March this yr & benign neglect over-winter (sigh)! Hoping for a better 2014 season!!!

What a beautiful combo bloomorelse!!! I just aquired 2 baby Blue Angels this Spring (will keep in a lg pot to grow in 'til 2014) thinking to pair w/ my grown Ramona. Your posted pic helped w/ my plans thank you!!!

Ditas, am I missing something or are the photos not labeled?
Thanks,
