Here I offer one of those things that I bought because I had never even heard of it. Turns out that there is very little that Google knows about this plant That is when I wrote this, but I am sure they will catch up. It is an African Vine from the island of Madagascar. It is listed as a Herb, Shrub, Vine, or Liana. I would call mine a vine.I would think that this plant is not hardy and therefore cannot even get close to freezing temperatures. USDA Hardiness Zones 10 to 11
