Australian plants growing overseas.
I had the opportunity to travel to Ethiopia, and what should greet me on leaving the airport but a stand of Grevillea robusta (Silky Oak), Acacia mearnsii (Black Wattle), a Melaleuca I didn’t recognize and a Eucalyptus species. (Who would have thought I would need Ivan Holliday’s book on Melaleucas in an overseas country?) Having seen these, my eyes picked them out constantly during our stay. There were forests of Eucalypts, attempts to keep Eucalypts going as street trees, and I noticed in some local nurseries, advanced plants of Eucalypts, Acacia and Grevillea robusta. In the grounds of the place where we stayed were Callistemon (Bottlebrush) species which looked like forms of Callistemon viminalis.
It was a difficult exercise to determine what plants were the naturally occurring species in the country side of Ethiopia. There had been much clearing of vegetation, and because the naturally occurring plants were much slower growing, they were not replaced. The need for wood for fuel and building supplies compromised the revegetation programmes.
Over the years many Australian species have been propagated in foreign nurseries and proved to be popular garden and pot plants for gardeners interested in the foliage and many unusual flower forms.
