Disphyma crassifolium (Rounded Noon-Flower)
This is another of the Australian Native succulents. This one is found on saline soils, rocky cliffs at the sea side and saline soils inland. This is a very hardy plant being frost and drought tolerant. It is especially good for areas where salinity is a problem. It would be good on an embankment which is the use I have for it. The plant makes roots at each node where it touches the soil.
The leaves seem to take on the reddish hew when it is in a dry position.
