This is the first record of this plant in the ACT. Native to the Mediterranean, it was first recorded as naturalised in New South Wales in 2009 from near Orange and more recently in 2014 from near Goulburn. It is capable of becoming a major roadside weed and possibly other areas.

A flowering plant, not a cryptogam.

This will be a Crassula (Crassulaceae), but I don't recognise the species.

Crassula. Thanks. It was tiny, growing near old basketball court. I will take more notice this coming Spring.

The flowers look more like Sedum. I am not familiar enough with introduced plants in the family Crassulaceae to make a judgement call between Sedum and Crassula.

This potentially significant weed also occurs in Victoria. Steve/Jenny worth eradicating this plant if possible let me know if you need assistance. A paper on its NSW naturalisation can be found at

Beth - thanks for this very significant posting - it had us stumped for a long time as it is a new one for the ACT and pretty new for NSW. Have the numbers expanded since October?

Hi Michael. I haven't noticed any since this sighting. I presumed the plant died back after flowering as in January there was no trace of the plant I photographed. I will make a point of having a closer look around over the next few days. Occasional weed spraying happens so perhaps it has been poisoned.
