Wisteria macrostachya, sometimes referred to as the Kentucky wisteria.
Why is it impractical?
This is a woody vine that grows up to 25 feet so it will need some support, some strong support.
I've just about figured out how I'm going to provide that support. I need a bit of lumber, some strong nails.
In fact, I've figured out enough about the support to convince myself to go ahead and plant the wisteria. So I planted it.
Now I've just got to finish building that support before the wisteria really gets growing.
