The "Rosea" form of the Red Ironbark is a seed selection that is red flowering. In all other attributes, it is identical to the species, but typically will grow slightly smaller. The growth is normally upright on juvenile trees, but trees begin spreading with age and can become 15m high and 15m wide. The bark of this tree gives it its common name; Red Ironbarks have deeply fissured plate-like bark that is a rusty red beneath and black on the surface. This bark contrasts well with the foliage, which is dark green to grey-blue. Frost hardy we think to about -6°C
