Looks like clay to me.
Have no idea what the wisteria's roots would do to a planted Trachy there.
But wisteria's top growth--at about 15 to 20 feet a year, needing a tall stout arbor--would soon enclose the entire area in shade.
Hope others chime in here.

If you drink, don't drive. Don't even putt.
I did the old mason jar soil test, turns out my soil is about 10% sand and 40-50% clay...so it might be ok...if it matters, there's only one or two places in my yard that turn swampy...and they're nowhere near where I wanna plant the palm...thing is, the wisteria has grown like crazy, so I can't really imagine the soil is too bad...
I'd make an entirely new bed for the Trachy away from the wisteria bed.

I suppose you ran out of patience and decided to plant them anyways eh?...lol

You're not going to hurt the Wisteria; they are tough. It will be more a matter of the Wisteria out-competing the Trachy. Anyway, do-able.
Lol nope;) I'm still trying to find another place:P Thanks for the advice/help everyone, I really appreciate it!
