Tree/Shrub, evergreen, broad columnar Height : 2m to 16m included Origin : Pacific Islands, Southeastern Asia, Southeastern Australia Environment : seashores, sandy slopes, open hills, on dry, sandy calcareous soils, sometimes on volcanic soils Climate : warm, temperate; very tolerant of salt and of windswept locations.
Notes : In spite of the needle-like leaves, this tree is not a conifer, in fact, it is much more similar to broadleaves. Being an excellent windbreak, Horsetail Casuarina was introduced into the coastal regions of other warm areas of the world, where it quickly became an invasive species, like in Florida. The deep digging roots can erode and split apart rocky cliffs. The wood is used for fencing and it’s also an excellent, hot burning firewood.
