what about trachelospermum jasminoides? Here it is called (I translate literally) "fake jasmin" because it really looks like jasmin. But contrary to jasmin it is hardy, tough, drought tolerant and imune to diseases. It is evergreen, it blooms in summer and is VERY scented. Sometimes it gets a few months before starting to grow, but then it starts. A very easy plant. You can find a picture here (from google): Here is a link that might be useful:

liz, if the "seedling" is as small as i think, you will need to nurse it in a pot for one growing season before planting in the garden. my personal experience has been that tiny clematis planted direct into the ground have high mortality or generally don't grow their root stock as vigorously left to the elements as they do pampered on my deck for a year...

Well, there's a guy on here, Botann (sp?) who says his miniature ivy ended up fruiting and seeding and going crazy and reverting back to English Ivy so there may be something to this, but I wish the websites and nurseries would explain that. It's so hard for a newbie like me to get correct information. I've spent an insane amount of money on my yard and freak out when a tree dies. Not going to rip anything out! Seems with an array of sharp tools I can control these plants. Just 1/4 acre with the house taking up a lot of that area. Your wall is the type more and more frequently being used to terrace new housing developments and there must be many ppl looking for something hardy that will grow up these walls and look good without ridiculous amounts of babying and maintenance. I've bought several varieties of euonymus fortunei in the last 2 months and hope they'll do their climbing thing. Looking each groundcover up in Google Images gives one an idea of how they can look, but doesn't usually tell one how LONG it takes to achieve that picture-perfect growth. Looks like the vinca will need to be pruned out of other plants like heather it's overtaking. These are raised beds so pruning is very easy. CostCo had nice grass shears and they're snip snip easy to use. Also got a wheeled weeding bench so can zoom down a line with shears for edging. One thing about these garden forums -- posters seem to attack a lot of plants and trees as invasive. That makes me laugh because every day the 'wild' around here is extinguished, visibly, and replaced with dead things. If only the plants COULD win! Not a chance anymore unless avian flu pandemic wipes the virulent pest humanimal off the planet. If ppl were still into gardening and installing beautiful landscapes with sprinkler systems it might be different. When I moved to Portland in 1984 there were so many estates with lush green landscapes and ppl took pride in their yards. But now the outdoors is a "bother" and ppl no longer cognize beauty or God's magnificent glory in old-growth natural riparian forest or any other original undisturbed remnant of Eden.

I was going to recommend a climbing rose. But most of them have thorns. Unless you go for Zephirine Drouhin rose, which is virtually thornless. However, I don't know how it will fare in your climate. You can check on the rose forums. There are several fragrant clematis. Clematis Montana, Clematis rubromarginata, Clematis sweet summer love. Other vines, are Moon flower (Ipomoea alba), and other less fragrant honeysuckle vines. You need to check for the toxicity of some these vines, for children and animals. Go to the fragrant plants forum and ask for more advice.
