After four years of intense growing.

The roots of a four year old seedling is rather swollen.

Did not look much when I received it.

Five years has added quite some to the base, but not much to the height.

This member of the Xanthorrhoeaceae family was described by Ferdinand Jacob Heinrich von Muell in 1864. It is found in the southern part of Australia, growing in sandy or other well drained soil with little to some water and lots of sun. The stem will (in 100 years or more) grow up to one meter in height and 25 centimetres in diameter, the leaves to 60 centimetres long. The flowers are crème colour, and seeds seems to be the only way of reproducing.

The genera name from the Greek xanthos; 'yellow' and rheo; 'to flow', referring to the yellow gum that can be extracted. The species name means 'with four angles'.

*)Accordantly to the latest taxonomic system; APG IV 2016, Xanthorrhoeaceae is now part of the Asphodelaceae.

My plant tend to grow the most in winters.
