Yea they grow around here i just never thought of using them until ididn't have a chameleon anymore. I am hoping to get a louie and camille baby in august. anyway if anyone wants some of these vines i would be more than happy to cut you some if they do not grow in your area. Ican just ship them, it shouldn't be much they weigh almost nothing.
By the way they naturally curl around each other and are very strong. I am pretty sure they last forever too. My grandmother makes wreathes out of them because they are so bendy and pliable.
