Threatened Native Plants is a garden at 102 Hill Road in Manurewa, south Auckland, and its website is devoted to New Zealand's threatened native plants. The site sorts species by conservation status, from nationally critical to naturally uncommon, and gives growing tips, care guides and botanical notes for many of them. Among the species it covers are Hector's tree daisy, of which fewer than 50 wild plants remain, and kākābeak, a critically endangered shrub with red parrot-beak flowers.
The website names seed banking, habitat protection, pest control and cultivation programmes as the main conservation efforts. Growing threatened species in a garden is one of those cultivation efforts, which is where a place like this fits in.
