I posted a picture of our potted grass tree’s flower spike here it is about 1.8 metres high. In comparison, I took the above photo at work this week, this amazing spike reaches over 3 metres!

Xanthorrhoea
Uniquely Australian, the grass tree, Xanthorrhoea, is at home in the red sandy outback. Our neighbours in Sydney gave us a potted tree to commemorate our living in Australia for ten years. This the second time it has flowered in seven years. They typically grow around one centimetre per year, and can live for many centuries.
