I have read that akebia quinata is 1) a garden thug and 2) lovely if a tracery effect is wanted. Which of these is true? Is it considered a thug because it is, like japanese honeysuckle, vigorous and roots where it touches the ground? I've just planted one on the north facing side of my 5' high fence. Would it be better to plant it along my 8' high fence adjacent to (about 3 feet away) the north side of my house?
