This is an Xanthorrhoea (X. johnsonii) in the bush near me. It is reckoned to be a relative of Hemerocallis.
Peering through the bush, early colonists thought they looked like someone holding spear.
They are prized garden plants but slow growing and do not like being moved at all. This has saved them from over-exploitation.
The plant with a finished flower spike carrying seed (to 6', 2m).
The skirt, as it is called. There is usually a trunk below it.
