If you go back to garden watchdog and search for Klehm's Song Sparrow Perennial Farm you will find them. I tried to post a link but gardenweb thought it was spam. I've never ordered from them so can't offer a personal opinion.

Hi, I ordered from Klehm's last fall and was well pleased with the quality and size of the plants. The shipping was on the high side (I thought!), but the box was much larger in size than expected and very well packed. I think the clematis was in 1 quart pots. I hope this helps.

I have ordered from them before and liked both the size of the clematis and the customer service I've gotten. Their catalogs are also lovely.

I've purchased clematis Florida Sieboldi in 2004 and H.F. Young in 2003 from Klehm's and both of these clematis are still thriving in my yard. Although their shipping is on the high side, they have very good quality plants.

Thank you all for the feeback. I did finally find them on Garden Watchdog but didn't see too much feedback within the past 2 years on clematis that buyers received.
I do agree with others who mentioned the high shipping costs. Scratching my head on their pricing for shipping when compared to other well known sites. They are at least double in cost.
Is there something special with their shipping? Plants appear to be the same size as you would buy at other online sites.
