There are nice cultivars bred for looks and other qualities but it's not one of them, just something that commonly grows over trees in forests here, like this one near where I live, large specimen, climbed over 20 meters to reach this pine's crown.
I have more of it on my Northern fence, it's a really good pollinator attractor in mid-late Autumn, there are so many of them over it at that time you can hear them from 10 meters away.
I wouldn't recommend planting it where it's an invasive tho, it spreads really easily thanks to birds, we have to remove new sprouts under trees from bird poo every year.
