How big is the cutting? It is not a massive vine - more in line with a Clematis that's a couple of years old. You will have to cut it away from whatever you choose to grow it on, so consider that when you choose a trellis. A 6' dead tree sapling, stuck about a foot into the ground, works well.

When you need to cut it back, to bring it indoors for the winter, you can just cut the dead branches away from the vine and it will re-grow the following years. Watch for mealy bugs - they LOVE Mandevilla!
