1. Beautiful.... The possibility of such beautiful gardens would be the one reason I'd leave Colorado

Though I've seen some immaculate landscaping and beautiful grounds out here, that would be hard to obtain and maintain.

But, no... I like my semi-arid environs and the mountains. Beautiful wisteria though.

2. I don't see why you can't grow wisteria in Colorado.

https://www.whatswhyhow.com/what-zones-can-wisteria-grow-in/
Chinese wisteria grows best in United States Department of Agriculture Hardiness Zones 5 through 8, where the average low temperature ranges from minus 20 to 20 degrees Fahrenheit. Japanese wisteria flourishes in hardiness zones 4 through 9.

There! If you know zones!
That said, they go dormant in winter. I recall seeing them in New England, and pretty much everywhere.

I lucked onto a very straight stemmed one and I'm training it into a wisteria tree. You can pay quite a lot to buy one already trained, as it takes years.

The NEATEST thing about wisteria is that they make seed pods, which fall and curl up. As they dry, they develop a lot of tension. So, they just explode whenever they are ready to do so, releasing the seeds.

Ask a local nursery. The vines come in containers, with a stake to hold them up. I made a sturdy tripod of three plant stakes. The wisteria trees (if you keep them pruned) don't spread all over, but the spreading habit is real pretty in the right place, and with a very strong support structure or fence.

3. Maybe so! I always thought they needed major humidity, though. Maybe I'll try it

5. I have never heard of anyone watering a wisteria unless it's a tree in a container.

Of course, prolonged drought is bad for everything.

Easy enough to check on these things. The first page of results at DDG (I refuse to use Google) will have lots of links.

4. American wisteria is hardy to zone 4

I'm currently growing about 50 seedling from a large trellis nearby, just south of Minneapolis. The plants covering the trellis have survived -30F temps in the past 5 years

It's also non-invasive, unlike the Asian species. I'm also planning on growing some as tree forms!
