Growing native plants for green roofs requires a knowledge of how one species can difffer dependent on it’s natural ecosystem. On inspection, I also notice that a coastal version of the same species has much shorter distances between leaf nodes and branches. In one photo below you will see the plants side by side, on the left leaf nodes are 8-10mm long, on the right leaves are 3-5mm apart. Unsurprisingly the coastal version is a shorter and bushier shrub, surviving extreme winds and salt. The variety growing in Western NSW, I know survives in temperatures in excess of 50C in the shade. Thats why I will be planting this shorter variety on coastal green roofs, and the other variety on hot roofs in Western Sydney.
