Bulbetts of this wonderful bulberous vine, Dioscorea batatas, that I grow in pots on my patio. The leaves are pointed 1 wide and 2 long and are very shiny with deep purple veins. This plant has never blossomed for me but does produce very small tubers along the stem as it grows. This plant will form a vine for the patio and along a trellis or quick growth for a covered patio area. Zones 5-11
