Eucalyptus haemastoma:
is known as Scribbly Gum. This is one of a number of smooth-barked
Eucalypts that have mysterious marks on the trunk. The larvae of a small grey
moth burrowing in the bark cause these marks. Scribbly Gum is a small to
medium tree. It has an attractive, crooked trunk; glossy leaves and white
flowers that appear sporadically throughout the year. The flowers are rich in
nectar and are useful for honey production. Koalas will eat the foliage.
Eucalyptus haemastoma is restricted to the Central Coast and Tablelands
of NSW. It is a prominent tree in bushland around Sydney. The species could be
grown as a specimen tree that would develop into an eye-catching addition to
your domestic environment. It would be interesting to observe if the scribbles
develop on plants grown out of their natural range.
Propagate from seed.
Eucalyptus rossii is
another species that insects use as a writing pad. This is a native of the
Slopes and Tablelands of NSW. Eucalyptus rossii is prominent in the
Warrumbungle National Park.
