It grows well in Central Oklahoma, and where I usually see it is along roadsides in elevated disturbed areas. So, say, on the high side of the road, with some slope/drainage down toward the road ditch, in a place where there aren't many nearby
trees to shade it. In such places it grows into substantial thickets, maybe twenty or thirty feet long and a dozen feet deep.
From this I'm going to deduce that it wants well-drained feet and lots of sunshine.
