Altre informazioni

Xanthorrhoea is a genus of flowering plants endemic to Australia. All are perennials and have a secondary thickening meristem in the stem. Many, but not all, species develop an above ground stem. The rate of growth of Xanthorrhoea is very slow. However, this is often generalized to mean they all grow at the rate of about an inch (2½ cm) per year. After the initial establishment phase, the rate of growth varies widely from species to species. Thus, while a five-metre-tall member of the fastest growing Xanthorrhoea may be 200 years old, a member of a more slowly growing species of equal height may have aged to 600 years.
