Xanthorrhoea semiplana (Yacka, Grass Tree)
This photo was taken because it was fascinating to see the age of these Grass Trees. The walking path passed between these two trunks. There is moss growing on the trunks. I would love to at least see my little plant make the canopy of leaves showing on these.
This plant seems to be a very hardy one once established. The flower stalk can be up to two and a half metres long. They often have a kink or distortion in the spike.
