Eucalyptus MacArthurii is grown commercially for biomass and paper pulp.

I’ve grown them now for a couple of years and I am definitely in favour of experimenting with this variety. Those that were out during all the winter gales of 2018 / 2019 were remarkably resilient, with no noticeable wind burn. They developed sturdy stems quickly and so should require minimal staking if at all. NOTE also that my experience of Eucalyptus generally has been that they only become unstable if the ground becomes particularly saturated.

As in the photo below, they make grand stand alone specimens a trees in a large garden.

Also known as Camden Woollybutt from the area where they were first discovered and the appearance of the bark near the base. Eucalyptus which are native to areas where wild fires occur generally have thick fibrous bark to protect them. I would assume that as MacArthurii only have this thicker bark at their bases, that the wild fires they encounter are low level scrub and don’t become all engulfing infernos. The native range is quite localised to a small area in South Eastern Australia.

All of the photos above are from trees growing in Spain, though as I say, I have had very favourable results here in Ireland with even the young leaves having a thicker waxier surface which I find makes for more resilience to wind burn. So I am happy to be growing Eucalyptus MacArthurii for firewood logs and flowers for bees and insects which will attract wildlife.
