I had to respond to this post,your split leaf is gorgeous & huge.I don't know much about them except my hubby loves them & every time he see's one he says something.I have told him they are tropical and not hardy to our zone and i would have to pot it & overwinter it and we simply don't have enough room to bring it in every year.
I do grow a pot of 2 different varieties the plain green 'heart leaf' hederaceum v. oxycardium & 'mican' scandens micans.I believe i named them correctly,they live nicely together and hang about 4-5 ft. long.
I could just not say how beautiful your plants are!!!
