The name of your pink clematis is PIILU. See Clematis On The Web and look it up - there are some gorgeous photos of it. The info says it will reach 5-6 feet.
I have recently gotten really into clematis - after taking mine for granted in favor of daylilies and roses. There are so many uses for them and they can be put in amongst other plants. I have an old [about 20+ years] Mrs. Cholmondoley that I dug up in June to bring to my new home 18 years ago and it still blooms. It was the first plant I dug up and transplanted - at the start of summer. Its still here - growing and blooming. It was absolutely the wrong time of year to transplant but I had no choice. I just planted 3 that have been in pots since spring 2011.......and they are putting up new shoots like mad. I keep them watered, shade the roots. They seem to be doing just fine. My experience with them has been that they are tough plants and given optimum conditions - sun, roots shaded, water, fertilizer - they thrive. Good luck, I will bet yours will do fine. Natalie, that is a gorgeous photo of your Jackmanii!
