Outstanding Australian Native Garden BB LOVE this! Coming from this end of the world, have no idea what most of the plants are, but a good nurseryman should tell you and then it wouldn't be difficult to reproduce.
Let's have hanging plants partially covering retaining walls. Also, use for upstairs balcony wall. Casuarina Glauca "Cousin It" Cousin It is a groundcover form of the tough, hardy Australian native sheoak.
