I have quickly googled Western Chokecherry. From what I've found (hardiness zone 5 - 10) it is widely distributed plant. Don't know why it wouldn't grow where you are. A place in NE Okla called Sooner Plant Farm sells a variety called Canada Red, which is apparently popular as an ornamental tree because of it's reddish purple leaves. It's hardiness zone is 2 - 7. There is much info on the web regarding these trees. I don't know anyone personally who has them, but considering they were once a staple in the Native American diet, I'm sure they'd grow in Okla.
