1.My first choice would be Stephanotis floribunda.
2.Jasmine (jasminum)many varieties. All can be trained as a vine and are fragrant.
3.Star Jasmine (trachelospermum) Is a fragrant vine.
4. Hoya is good on a trellis. Very slight scent.
5. Honeysuckle (Lonicera) aggressive. Not as neat appearance nor easy to control.
6. Chinese Wisteria (wisteria sinensis) slightly fragrant. Attractive when in bloom. Aggressive.
I would plant a couple of different kinds on each post.

Good luck

Stephanotis, mandevilla, medinilla, gloriosa lily, jade vine, sweet potato, passionflower. All depends on if its in full sun, shade etc.

hi!

i already plan on using stephanotis for an accompaniment to my potted podocarpus. otherwise, i'd have loved to use it.

i heard of a vine climbing ylang-ylang, not a tree. do u think this will be ok? the space will have 1/2 day full sun, 1/2 day partial, & i plan on leaning the gazebo against the house.

do u think the ylang-ylang will be too aggressive for this & may even buckle the ground?

i would love to have a little variety otherwise.

thanks.

I like Queen's Wreath, Petrea volubilis. We have one here at Selby Gardens on our gazebo. It's the best wisteria substitute for color but there's no scent.

Here is a link that might be useful: Queen's Wreath

grapes, black pepper vine, passion fruit or air potato vines would give you something to eat eventually.
