The Sydney Blue Gum offers only a slight chance of success in most of our area, being reliably killed by frost at around –5 ºC, so that it is suitable only for the very mildest locations. It does, however, grow very fast, putting on 10–12 m in four years in Oregon (S. Hogan, pers. comm. 2007), and while doing so is attractive, the new growth appearing red before turning a good glaucous blue. As the name suggests, Eucalyptus saligna has a distinctly willow-like appearance when young, but mature specimens are beautifully straight, and important for timber.
