Nothing epitomises the image of Australian garden design more strongly than the wonderful avenue of Lemon Scented Gums Corymbia citriodora at Cruden Farm, Langwarrin near Melbourne. The twist in the driveway and the random spacing of the trees gives a hint of the character of the Australian landscape.
There are hundreds of species of Eucalyptus, most of which are native to Australia. The flowers on this particular species are a brilliant red color. Photographed at the UCSC Arboretum in Santa Cruz, California.
Eucalyptus erythrocorys or red-cap Gum - (Illyarrie ) is a mallee from Western Australia. It is a small tree, 3-10m tall and can be very ornamentail in a garden. The bark is smooth but can have a few rough patches where it persists on the trunk instead of being shed. The Illyarrie is notable for its big flowers which can be 5 cm across or more. They are bright yellow, being covered by a bright-red cap (operculum) in bud - giving the epithet erythrocorys (red-helmet).
