Kadsura coccinea

While the genus as a whole includes a lovely group of vines, this, from China's Nanjing Botanical Garden differentiates itself from the others by showing off red tints in both new growth and new stems, with the same showing in the winter color of the evergreen foliage. Small flowers produce whitish fruit on female plants but, really, that's not the reason for growing these. Another in the increasingly large arsenal of useful vines that don't immediately climb to the top of the nearest tree. Sun for best color though not half bad in shade with some some water where dry. Frost hardy in USDA zone 7.
