What could have been
So we removed the concrete drive, placed two railway sleepers along the length instead. We wanted to be able to park the car in the drive way occasionally and the sleepers help to prevent soil compaction (we navigate our wheels along the sleepers). Over the years different plants have featured along the drive, such as Wallaby and Kangaroo grass. A few Kangaroo grasses have persisted but not the Wallaby grasses. I then planted Microlaena stipoides, a clump forming perennial grass. It does quite well if I manage the weeds. In the peak of summer it dyes back completely and then re sprouts in Autumn. Pigface (Carpobrotus glaucescens) has featured too, but has done better along the nature strip.
