Hi Lois, the only one I have grown is Clair de Lune. It hasn't done well for me. I have heard lots of good things about Avantguard and Rosemoor on this forum. I have never heard of Ice Blue. For $8.99 I would put all of them in my basket and give them a try.

Avant Garde is a great clematis and I would snatch it up in a heart beat. I have treated Rosemoor as a type III since I got it and it doesn't seem to bother it in the least--a great clematis in my estimation. Don't have the other two so can't comment on them.

I have all of them but "Ice Blue"..get 'em..you'll love them...Lucky you..wished my Locals carried those and you have great prices for one gallons!!..Jeanne

At that price, get all of them and see how they do in your garden. :-) Clair de Lune is new here but is doing well.

Thanks to all of you. I plan on going back this week and hopefully they will still have something. It has been so cold here nobody is really in the planting mood yet.
