If you take a cutting of the mature tip of the plant, root it upright as LariAnn suggested, & grow it in direct sunlight to keep mature leaves coming. This is the observation I have from seeing the wild Syngonium podophylum here in Tumaco. Place it on the sunny side of the tree your going to let it climb, but honestly I would just watch the ones around you as inviting it into your yard in a climate where it is invasive may be a bad idea!
I would try the seeds though to try for a dwarf plant. That would be awesome to see mature.
