Saving the world's rarest plant

Saving the world's rarest plant

Two DOC workers have been battling to save one of the world's rarest plants.

There are just 67 of the hardy wee plants left in the wild and in the world and they are in one remarkable place called Castle Hill in the Canterbury high country.
