Tussocks at Caroline Bay are showing signs of new growth.
A large section of tussocks, planted at the bay to protect the sand dunes, was ignited by wayward fireworks last November.
Despite being singed, many have continued to grow, a pleasing sight for Timaru resident Denzil Paterson.
Mr Paterson said he had been reminded how hardy the plants were, having previously seen burnt tussocks regenerate.
He advised the Timaru District Council it was highly likely the tussocks would come away again, so it would probably not be necessary to replace them.
To prove his theory, he rescued one of the plants from the bay soon after the fire and took it home to his glasshouse, where he watched it come back to life.
Three months on, signs of growth in the form of green shoots can be seen across the bay, despite the plants still having charred remnants.
Mr Paterson and others had watched them regrow.
“The ones that were burnt have certainly come away,” he said.
