If you live in a frost free area, preferably over 10 degrees C, you can hang a plant in a hanging basket on a tree and with time it will grow onto the trees. This E.phyllanthus phyllanthus has rooted into a depression in the trunk marked with a red X and will likely grow all over the trunk at which time the hanging basket could be removed. I have found planting a plant directly on a trunk can work but it is a slower and riskier proposition.

This could be adapted to a house or greenhouse by putting the basket next to a dead trunk or slab of wood.

I just did this for my daughter in early March. She lives in Southern Florida- Pompano. She already grows Vanda orchids on the trees outside their condo. I brought her some cuttings of an Epiphyllum and found a nice clay pot for her. I got a scrap piece of pressure treated lumber and screwed it into the tree and then put the pot on the board. She just sent me a photo of the three cuttings showing signs of rooting already.
