Gardeners' Notes:

I was given this plant about 5 years ago. It was a piece that had broken off another plant. here in Greer, SC. IT has grown and is now growing up and along the soffit of the eaves of the house. I can not believe how hardy it is. No one expects to see this plant. I have to wire it to the house now because it fell over and broke two ice before. A very nice and robust plant.
