I believe the great majority of cuttings are rooted vertically since it is the way most cuttings lend themselves to. But occasionally a cutting will be unusual and a more imaginary method may have to be applied in the rooting process. I'm not exactly sure if this example is what your question was asking but I have a photo of a cutting I received that I found quite exciting. This cutting was not going to lend itself to the cup method I was using at the time and I did not want to trim anything from it to do so. I ended up using a small plastic storage container as a humidity chamber and laid the cutting in a potting soil mix just as if you would lay a hand with the ends protruding upward. Once green started to protrude from the tips, I carefully transplanted everything into a 5 gallon squat pot as its final home (at least for the next year or two) so as to not disturb it for a long time. I hope to show 2 photos showing this.
