Check out Jerry Meislek's website for information on styling Wrightia's. (
http://www.bonsaihunk.us/) Wrightias in the "wild" are more like bushes - no natural form of their own. I style mine somewhat like an azalea - any aesthetically pleasing shape goes, but try for "pads" to display the flowers. Except, since Wrightia's flowers hang down under the branches - "pads" translate into having space beneath & between the branches so that you can enjoy the flowers better.
I'm still working on mine - good luck styling yours!
