Urn Vine aka Dischidia are epiphyte vines which live on trees in Southeast Asia. Many of them have a symbiotic relationship with ants. Some of the leaves form homes for the ants. You can see a large bubble like leaf in the photo. Roots form inside these areas and feed on the ant waste.
They can grow to be 16′ long. They usually grow on some other plant such as a tree.
They prefer bright indirect light, but will grow in low light.
Wrap the roots in sphagnum moss and mount as you might an air plant or orchid. Water them when the moss gets dry to the touch on the top.
