Both Araujia sericifera "Bladder Vine" and Stephanotis floribunda would probably only survive winters in zones 10 and higher. I have a Stephanotis floribunda in a container here and I have to move it to a protected area when temperatures drop in winter.
I am in the Central Texas area. This pod hasn't bloomed so far. The vine that it grows on looks nasty and dead but the pods are green. We found them hanging from the top of a cedar tree. It is only in one area of the property and we haven't seen anymore around.
