dangar: like all eucalyptus the limbs are well known to break off suddenly so do not set up camp underthem. Limbs will break off without warning. This year at a school camp in Australia a teenage girl was killed when a limb broke off overnight

Exceptionally dark-green leaved Eucalyptus with thick, soft red-brown bark. Handles swampy soils and saline soils as well as drought. Very sturdy tree and makes a good wind break. Flowers mostly in winter, but can flower all year long.
