Grass Trees

Xanthorrhoea glauca, Xanthorrhoea pressii, Xanthorrhoea johnsonii

Grass Trees are very slow growing with mature plants being centuries old. Grass Trees only grow in Australia.
These remarkable plants have a lifespan of 600 years but are very slow-growing. 
The trunk takes a decade to form initially as it is composed of a mass of old leaf bases held together by a natural resin. It is then a further 20 years or more before the mass of thin, linear leaves rises above it. From then on, it grows only about 1-2cm (0.4-0.8in) in height per year. We have observed plants which have taken 27 years to grown 30 centimetres (one foot).

This plant grows to a height of over 4 metres and often has branches. It’s growth rate is only about 1 metre every 100 years. However, the flowering stalk grows at a rate of 2 – 3 cm per day reaching to a height of over 3 metres. Mature plants will result in flowering every 2 – 3 years. 
The Grass Tree attracts a wide range of lizards and insects that shelter in the plant’s massive foliage. The flowering spear of the plant attracts honey eating birds, bees, ants, and butterflies.

One of the casualties of clearing land is the unique Australian Grass Tree. Many of these plants are hundreds of years old. Removing these plants from the land prior to clearing and replanting them later is one way of saving the plants. By adding plants to commercial and residential land not only ensures the plants will live on for generations to come, they also make splendid features that require very little water and maintenance.
