I have seen an example of the strangling kind, in my friends' garden next to the sea in Halkidiki. The mound in the photo is covering a stump of an old poplar which died many years ago, it's quite impressive, it must be at least 5 meters tall (the grund to the left of the wall is about 1 m lower than the street). It was fantastic in October, full of flowers and bees, and smelling very intensely of honey. It grows quite freely there, like a weed, the ground is more moist than at our place a few meters higher up, but I have planted a few the seedlings from that garden along a fence I want to cover, they have at least survived the first summer (no watering).
This is surely not a cultivar, but the ordinary Hedera helix which is widespread in the Balkans, according to Polunin, and found in most of Greece up to 800 m. It was also the favourite plant of Dionysos, and in all the festivals held in his honour it was worn as a garland.
