Another unknown plant. This one I took a cutting from a sprawling plant between the curb and footpath when I went to the city for an exam. All down the street of this area were succulents filling gaps; around sign posts, holes in the footpath, at the foot of trees. Not sure if it is a succulent as it doesn’t show the same characteristics but I treat it as one.
