The grasstrees were pulled from the Nicholson Road verge before work began on the new dual carriageway last October, then stabilised before being cared for by Grasstrees Australia for the past 10 months.
Mayor Dave Griffiths said grasstrees were notoriously hard to transplant, so he was proud of the effort that had ensured their survival.
‘Grasstrees, in particular, really add to the landscape of our suburbs,’ he said.
The grasstrees have now been replanted into the new dual carriageway and verges.
Cr Griffiths said the exercise of extracting, stabilising and replanting them was more cost-effective and environmentally proactive than buying 29 grasstrees.
