I absolutely LOVE my trumpet honeysuckle as already recommended and pictured by applestar. The hummingbird visitors make this vine all the more attractive for me since I love seeing them zip around these flowers. I have ‘Major Wheeler’ variety and it blooms heaviest in May, but continues to bloom all summer.
My neighbor has the most gorgeous climbing hydrangeas and like mentioned already, they take a while to get established but seem worth it!
I planted hardy kiwis last summer and they’re too young to get any fruit yet, but they vines themselves are very attractive! I have a male and ‘Anna’ female variety. They’re very vigorous growers and have pretty red stems!
I also have the Carolina jessamine recommended by KeyWee, but it hasn’t proven to be evergreen for me yet. It has pretty much died to the ground the last couple of years, but this is the first year it has really started to take off so we’ll see as it gets more established! A neighbor has one that’s more established and really just gorgeous!
I would NOT recommend the cypress vine recommended by applestar for our zone (sorry applestar
)! I planted it 2 summers ago where I just wanted it to be an annual. I was pulling seedlings all last summer trying to get them before they bloomed again and spread more seeds! They were in my lawn, sprawling all over my gardens, everywhere!!! There is a morning glory, cypress vine hybrid called cardinal vine that is an annual and has been much better behaved for me and didn’t reseed at all. Thought it could have just been luck! The leaves are a really unique shape and the blooms are very similar to the cypress vine and draw the hummingbirds as well. You mentioned wanting a perennial so maybe not what you want, but they will fill the trellis in a season and the seeds aren’t very expensive.
My passionflower vine didn’t come back either and it is supposed to be hardy to our zone
