Xanthorrhoea fascinate me. They are native to Australia and there is a huge forest of very old plants about one hours drive from here.
The plants grow very slowly, about an inch per year, and by the size of plants in this forest they would all be, at the very least, 200 years old.
Their trunk is formed from the accumulated bases of the shirt of leaves that grow from the centre of the plant.
Bush fires stimulate them to flower and a long spike is pushed up from the centre of the trunk through the skirt of leaves. Then this spike bursts into flower.
While bush walking after a fire recently I came on these plants and most were in flower.
Thank you for you visit and the so nice comment. very much appreciated.
