I ran across a very good smelling version of this plant in West Lafayette, Indiana, growing up a garage trellis. Tried to move it to my farm. Two problems. One, it doesn't seem to compete well with other species. Two, it has some cold sensitivity, roughly zone 5.
Please see my item on honeyvine milkweed. Your experience is quite believable. It surely comes back each spring there as long as its roots are killed or removed. It fits well with other native species but can't compete with Japanese honeysuckle and such invasive plants. My interest is supporting native bees, butterflies and other pollinators. Climbing species of milkweed do that quite well. They just don't provide a year-round windbreak or visual buffer the way the invasive, nonnative vines do. And they do NOT strangle woody stemmed plants in Northwest Arkansas.
