Perhaps twenty years ago, my ex, a real gardener, bought a sprig of an obscure vine at the UBC plant sale. It flourished and became my baby, even though I am no gardener at all. I am interested in getting another - now that the original vine and I are parted - and googling does not yield anything under the name I thought it had. It is from Chile, a vibrant, green, leafy vine which will cover the side of a house. It flowers are white. I thought the name was "stontonia". Can anybody help without further description? Thank you.
