I have a small hibiscus that I would like to train into a tree with the twisted trunk and I have no idea how to go about that. Please advise.
When you prune your hibiscus into a tree-like form with a single trunk, it is called a standard. There are even braided topiary forms. To achieve the twisted shape, you will probably need to create a support or frame.
The following general information on pruning comes from Tropical Hibiscus:
"While the tropical hibiscus can be pruned any time, probably the ideal is the earliest where the resulting tender new growth will be safe from cold damage*. For shaping purposes, some growers will prune the longest third of the branches and return in 4 to 6 weeks and prune the next longest third. Only sharp, clean shears should be used. A clean cut should be just above and angled down and away from an 'eye' or node. (A node is the junction of a leaf and the stem. There is a small bud in this junction that is activated after pruning.) Cutting above outward pointing "eyes" will encourage growth in that direction. The new growth resulting from pruning invigorates the plant and will provide a source for many new blooms."
The American Horticultural Society's Pruning & Training (edited by Christopher Brickell and David Joyce, DK Publishing, 2011) describes the technique for creating a braided stem:
"Form a braided stem simply by braiding together three flexible young shoots. Select the strongest three on a multistemmed young plant, and remove the remainder. Single-stemmed plants can be cut back hard to produce multiple stems."
The book also describes what is called a "barleysugar stem," which may be more like the twist or spiral you envision: in this technique, "use a sturdy wooden pole with dowel pegs inserted in a spiral along its length. Train one or two stems around the pole, holding them in place by looping them beneath the dowels. Remove the pegs and the pole in sections when stem growth has hardened."
