As to wood, the material i find very good - but of course as an English native bush it may not be found everywhere -is gorse. A prickly bush in the pea and bean family. It grows on the moors and heathlands here, which often burn in dry summers . Usually the thicker branches , up to say 4 cm diameter or perhaps a bit bigger, remain. They are very hard and I have to use a power tool to saw them, so will probably last very well. I have put some cattleya species on them, straight out of the flask, no moss, just cotton to tie them on, and the roots are 15 cm or more long within a year, and needless to say, the bulbs are getting bigger on each growth.
