Thank you all very much for your feedback!!! I am pretty sure that it is Campis Radicans -- as it looks identical to the vine on this campis radicans photo link. My interest stems from looking for a great vine/shrub to grow up the 6 ft. cedar fence in my back yard. I hope to achieve an attractive green look most (if not all) of the year --with some nice periodic flowering as well. I noticed this Campis Radicans growing on a neighbors fence and thought it might be a good choice for me. Any thoughts on a better choice? I live in the Denver area. Here is a link that might be useful:

my loquat has been a fast-growing tree that is about 10' tall from seed 5-6 years ago. i have a pittosporum tobira that has been pruned into an open, multi-stemmed shrub, standing almost 8' tall now. it is the variegated form and the soft green might combine well with the wall color. there is also 'wheeler's dwarf' if you want to try something smaller. i also think an oakleaf hydrangea could be something to consider. not growing too fast, it could be pruned for height and they grow naturally in the form you are looking for. japanese maples are a good idea. one with yellow fall color would look nice against that wall.

First let me say "Congratulations!" You have a blank slate, and a world of wonder ahead. We are in the same boat with new property. Please don't think me negative. Just sharing our experience. We just ripped out tons of tall vining hedges, never to be seen again, and get the "thumbs up" from all the neighbors! Think beautiful house, hidden. There were various hedges, some vining, some not, but all invasive. Over 500' of stuff to remove. Not cheap, and not cheap to replace, either! We are going to do an all dwarf citrus hedge behind the frontage wrought iron fence, and mix the types of citrus. The hedge will be topped at about 4-5', and we will lose some fruit, but not all. It will stay green all year, and that is the idea. I wouldn't mix a vine in there because vines climb anything and could strangle your citrus... Plus rats live in vines. They love that inner dark. Citrus are airy, so not so tempting to them. I think the green of the podacarpus would look great among citrus, but there will be gaps because citrus grows sort of as wide as it is tall. Good luck! I'm sure you will get lots of responses! Suzi

Yes, let me second that:"it will grow over everything." I purchased this vine many years ago because I read that it was a good hummingbird attractor. It now is huge and grows over many of my trees and those of my neighbor. I have never seen a hummingbird use its flowers. Perhaps they attract hummingbirds since they look like they should be good flowers. The vine is very pretty this time of year in Central Florida. In a month or so it will stop blooming for the rest of the year and then it will be pretty much unnoticed.
