This vine has a "winged" stem cross section, -it has very purple leaves and stem when first growing in the spring. It also makes areal tubercles, - It is a very rare and beautiful food plant, -the outside of the tuber looks brown like the wild Dioscorea alata, but the inside of the tuber is very purple. This Yam is used to make Indian , [as well as some other cultures, from tropical Countries.] native recipies. - It took me years to get a start of this --but it is very beautiful, ---
