appropriate place for clematis?
Last fall I cut down a wisteria vine that was threatening to take over my front railing. I'm considering replacing it with a clematis, but I'm not sure if it's an appropriate spot. I am attaching a photo of what the wisteria used to look like, but you can't get the whole picture so I'll try to describe it as well.
My front stoop is a concrete base about 3 feet high. There is an approx. 3.5 foot wrought-iron railing on top of that. I would like the vine to grow up that height (more than 6 feet total) and then grow sideways to adorn the railing (as the wisteria is doing in the picture).
The base of the plant would be in a mostly shaded spot (to the right in the photos). The railing gets sun for most of the day, at least 6 hours.
Does clematis commonly grow long enough for this, and will it train horizontally? Does this seem like an appropriate location? If so, I'd love any suggestions for varieties. I'd prefer something with a lighter-colored purple or pink bloom. Thank you!
