Alabast. It is just beautiful. Large, creamy white flowers. I purchased mine at Donahue's. You can order online.

My favorite is Arctic Queen--beautiful white double clem. Visitors always stop to admire it and exclaim over its doubleness.

Huldine would be my choice, the flowers aren't huge but they're beautiful and mine flowers until hard frost.
It does however have red veins on the back of the flower.

Here is a link that might be useful: Huldine

John Huxtable does well for a lot of people.

Hudline IS my most vigorous white of them all..

Huldine

Thanks !

Of these: John Huxtable , Arctic Queen,Alabast and huldine
which white has the longest bloom time?

Hope all of these can vine by themselves(not a spreader)!

Quote:"Hudline IS my most vigorous white of them all..

Does it mean vigorous grower or bloomer.?
I am gonna buy huldine , where can I get the best /cheap plant?

Arctic Queen is the most gorgeous Double White. I planted once the first week of may next to an Arbor. This bay has
taken off and climbed halfway up the Arbor and is in full bloom. She has tons of buds forming everywhere. OMG I will be
getting many more of these. The flowers are huge, and it is producing buds on both sides of every junction, where the leaves come out.
It is reputed to be the most florific of the Double Whites, and is not suseptible to the dreaded Clematis Wilt so it says.

One of my favorite whites is 'Marie Boisselot' aka 'Madam le Coultre' this one has large flowers and a repeat bloomer. I've been looking for another one to replace the one I lost about 6 years ago but haven't found it so far.

i think Marie B is one of my favorite clems, certainly one of the oldest.

For the last 3 years she has given me at least one semi-double flower as well as a multitude of big single flowers.
This is the only picture I have of her on photobucket, from 2007.

But this Spring there were no signs of life when the others were leafing out. So I trimmed off a little of the vines. The next day a little bit more, and so on until I had a foot high thumb thick piece of brown sticking up from the ground. I thought she might have bloomed herself to death last year.

I pulled out the ivy that had spread toward her stem & kept watering when it was dry, and sprinkled some alfalfa pellets on the ground near the stem. Was hope some new shoots might come up near the seemingly dead one, but it was not to be.

Then one day about 2 weeks ago I spotted what looked to be a green dot about half way up the brown stem. And little by little it has grown to about 1.5 inches & looks like it is trying to put out leaves.

I know I won't have much of a show this year, if any, but I am so happy she is still alive.

Before I saw the spot on the stem I was looking at clems at one of my fav nurseries & noticed a small but healthly looking Alabast. I thought I would plant it about 3 feet away from Marie's spot, on the otherside of the brass bedpost. It is doing well but not flowering yet.

And then I learned that Alabast is a cross between Marie & Henrii. Probably will have somewhat smaller flowers than the 8 inch wide Maries.

So maybe you could find an Alabast until you can get another Marie.
