I have Dawn. For me, it starts out a very pale pink and fades to white. I like it, but it is by no means long flowering. The photo from Brushwood, linked below, is accurate in my experience.

I think you'd like Clematis "Pink Champagne" aka "Kakio" MUCH better than Dawn...Jeanne

This is Dawn. She was planted last year as a two year old purchase. It is planted on the east side of the wood shed heavily shaded by an apricot tree. I think my mother has it on some sort of water system but I could be mistaken. The tap sits immediately to the left of the plant.

My mother and I have determined that soil content plays a very large roll in the final coloring of flowers. We determined this simply by comparison as we both have several plants in common and I live 20 mins south. My soil is "city" soil ammended with my own compost.

I'm not getting any "Great plant! Snatch it up" vibes, so I think I might find a better white. Thanks guys!

Try Huldine, campaniflora, or Alba Luxurians for whitish colored clematis. I couldn't live without any of them. Huldine is white with pink ribbing down the backside, campaniflora is a white to white with a purplish overcast, and Alba Luxurians is white but the early flowers have green coloration on the ends. The green color disappears for me once it warms up and stays that way. All three are type III pruning so you just whack them back in the winter and being type IIIs, they are much more resistant to succumbing to wilt.

Huldine is on my list. Will she bloom with a once-blooming climbing rose (Dr. Huey)? Or should I see about a white type I or II?

Ladychroe, I am not a rose person so I don't know diddly how the pairing would work out as far as blooms go. Perhaps someone who knows the blooming habit and time for this rose could help you more than I. The only rose I grow is one that is a scrambler that I took a cutting from a neighbor's plant and got one going! LOL

I prefer Growing the Pruning group 3's with my roses but saying that I do have some 2's planted with them..I have both Clematis "Huldine" and "John Huxtable" planted with my red climbers "Red Eden" and "Tess of the d'Urbenvilles"..you'll like either white one and they are both vigorous...I think "JH" is a bit more than "H"...Jeanne
