Grasswort Lilaeopsis novae-zelandiae
Endemic. Not threatened.
Also known by several other names, including tape measure plant or micro sword, it is another subtle, small endemic dune wetland herb and at home in only a handful of places in the Dune Garden.
One of these locations is always findable, as the others tend to come and go depending on the wind and sand deposition. Like many of these small herbs it has tiny 2mm subtle white flowers, which you have to look closely to find them.
Some related species are common plants for aquarists, but care needs to be taken that none are allowed to escape, and disposal needs done carefully.
