In Feb 2010 I tried to graft an epiphyllum on a trunk of a young
Myrtillocactus Geometricans. It survived so far, hopefully I will bring
it to bloom sometimes. Blooms will be reported

It certainly looks healthy. What was your purpose? Does it make the
Epiphyllum a more convenient plant to grow indoors?
