I think pink Chilean jasmine do not have strong fragrance.

Mehetabelle,

Many people want thorn-less roses. Actually there are: Lady Banks' Rose (Rosa banksiae) is one such plant.

Pink jasmine = jasminum x. stephanense? I've never smelled much scent from this one, and there are a bunch that'd be hardy in your zone.

Here are my thoughts:

1. They're vines; if one gets too ornery, you can just cut it back.

2. If the bloom times overlap, they have to look and smell good together -- white is probably a better blend with other colors than pink, but hey, it's a personal thing!

3. As long as both plants have enough root run, and you're good about watering, you should be OK.

If you go for it, send a pic with blooms, it sounds like a neat idea!

Jim,

Chilean jasmine is Mandevilla Laxa. They are not real jasmine. See linked images.

Hi Mehetabelle,
Sounds like a good idea. Pink jasmine (I presume you are referring to J. polyanthum) is not that fastidious so I guess it won't be a problem. I'm sure there will be an interesting mix of scents, too. Another idea would be honeysuckle (Goldflame)although it is supposed to be deciduous?

Hi, I am referring to J. Polyanthum. Very fragrant, easy to grow and propagate. Wonder if the roots are deep enough to compete with the rose? What climbing, fragrant vine has shallow roots?

I have Clematis combined with my climbing roses with no problems at all. I would not hesitate to combine with J. polyanthum if it was reliably hardy here.
