Hello,
I am wondering if anyone has managed to grow tropical plants in the
Seattle,WA, or NW USA area ?

Are you aware of any resources that I can contact to do the same ?

websites, ppl, nurseries- anything.

I am particularly interested in guava, papaya, jasmine and banana...As
for the banana I dont much want them to flower and bear fruit as much
as I like to see them all green and happy. I am hoping to have some
measure of success.

Or is it a pipe-dream ?
