perenial creeping vine
I am looking for the identity of this vine I have in my yard. It has few leaves at the bottom and throughout. Mostly it is light green woody with thorns. the tendrils it produces make it a great creeper onto neighboring trees. It is quite attractive when using it to make decorative wreaths for the home, as the woody vine is not dark like grapevine wreath but very light green. Can someone help me find the name for this?
