I would like to find the best vine to cover a fence. I want it to be fast growing and to be an evergreen. I'm considering Star Jasmine but cannot determine if it will winter well in west vancouver?
For leaps and bounds growth behavior your best bet will be Clematis armandii. Noting that any climber placed on a structure will need ongoing pruning and training to produce an attractive effect.
Yes agree with Ron B beautiful scent in bloom maybe mix in a honeysuckle ? We share a fence and both are twined together I think it will take work to make it grow horizontally I think they naturally want to scramble UP UP up! that said — depending on location and wind and how close to Howe Sound cold outflow (winter) — the clematis armandii that previously thrived certainly died back severely during the snow ice of 2021/22
