Re: growth rates - you hear it applied to all sorts of other plants, but this saying truly applies to clematis: the first year they sleep, the second year they creep and the third year they leap. It takes time for a clematis vine to become fully established and you will most often get your best results both in vigor of growth and production of flowers from year 3 onward. In the Seattle area, there are few locations where one can't grow clematis. Just avoid areas that receive too much shade - light shade is fine for many types. Also areas that may receive too much root competition from other established trees and shrubs. And understanding the reason behind the coda of shading the roots expands the possibilities - it's not so much as the roots requiring shade as it is not allowing the soil around them to dry out. And shady soil generally holds moisture better than open, sunny soil. But if you water appropriately in summer and mulch the root zone well, you can plant clematis in a full on, full sun southern position without fear. A couple of other notes on new clematis: prepare a generous planting hole, well-enriched with organic amendments. Plant the vine 3-4 inches below the level it was in the container, generally up to the first set of leaf buds. And prune all types of clematis hard after the first season in the ground. Both the deep planting and the hard pruning will encourage the development of a healthy root system and the production of additional basal shoots, increasing resistance to wilt problems. As to trellis or support size, research the expected size of the clem of your choice and select a trellis or support accordingly. And even this is not a hard and fast rule but merely a guideline. I've grown larger types of clematis on rather short supports - they just grow to the top, then cascade over, making a waterfall effect that is pretty stunning come flowering time.

I love akebia too; have one on an arbor and one on an obelisk. So delicate-looking. My new porch railing has a lattice insert, floor to ceiling, similar to yours. It faces west; gets lots of sun. Just put a jasmine stephanense on it. So far - so good. It even has a couple of flowers already. Looking forward to lots of warm nights sittin' on the porch, smellin' the jasmine. Not fond of clematis & roses, just because they are everywhere on my street I guess. Every one of the Clematis is beautiful in bloom, though, and they are pretty much ignored by their owners. Have 2 climbing roses on chain link fence that I can't kill, try as I might. Neighbor doesn't want them on the fence because they scratch him :0 Can't dig them out because they are growing under the fencing. Tied black plastic bags around them (to keep out light) and a bucket upside down on top of them for two years. Opened them up this year and there are dozens of pasty-white, curled-up runners just waiting to go! Refuse to use chemicals, so maybe I'll just paint the buckets in psychadelic colors and call them garden art.

Any idea

I can't tell anything from the photo. Are you sure that the rose is grafted? If you are, the only way to tell is to dig down to the base of the cane to see exactly where it is emerging, Or, wait until it leafs out to see if the foliage matches the variety.
