A plant that requires propping is a plant in need of pruning. Stakes are a temporary solution that look ugly and only have to be replaced later with even longer stakes. Pruning is the most neglected part of plant care because so many folks are convinced they will kill their plants if they prune incorrectly. In fact, pruning has no affect on the health of a plant; it only alters its appearance. Most plants will put out healthy new growth just below the point on any stem where you make the pruning cut. It's not hard or complicated.
For all of you who have plants propped up with stakes, ties or leaning against walls, learn to prune. It is not that hard once you get the courage to try it.
