Thanks for your response!
So I'm not really sure if I'm actually looking for one that attaches. Here's more info for context...
I live in an apartment building so don't have years to wait for it to grow (and also don't want to irritate the landlord too much with a vine that takes over the building).
I want the vine to grow very fast -- I want to see it grow horizontally across the balcony wall within a few months. I'd also like it to grow up a thin rope or wire (see photo -- the red line is an example of where I'd hang the string).
Do you know of a very fast growing vine to accomplish this task, keeping in mind that I'm in Zone 7b, with partial sun (afternoon and evening), and the vine will be growing in a container?
Thanks so much for your help!
