We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Yes, they're lovely. Yes, they attract hummingbirds.
However, they also attract wasps, ants, are a bug highway, spread their seeds everywhere, and like blackberry vines, grow everywhere and are hard to eradicate. So PLEASE don't plant them on a fence you share with a neighbor.
I have one that covers about half a biggish pergola. The only problem I have is that my wife likes to really prune it back, so most of the flowers are on top of the pergola and that makes it hard to see the hummingbirds. Given its placement it is unlikely to cause much of a problem, but I knew it was invasive when I bought it, so I placed with some thought. Heavy clay ground, wall next to the kitchen [we really prune along there], not near anything I care about.
Provides nice shade during the heat of the day [well, it would if we had any heat this summer], too.
