Some of my favourites at this time of year are the spotted gum (Corymbia maculata) from eastern Australia and the yellow-scented gum (Corymbia citriodora) from Queensland. Both are widely planted ornamental trees in Australian gardens. There is a great avenue of lemon-scented gums in Kings Park, Perth, but they are common in most cities here. In December they begin to shed their bark, first little blisters appear, then they burst on one side and begin to peel up, revealing a myriad of beautiful colours underneath, reds, beetroot, carmine and oxblood, russets, limes and greens, avocado and asparagus. Some of the outside bark hangs for a while but in the end it all departs to develop a smoothe new coat of cream which slowly changes back to grey before it all starts again next summer.
