Plantago gunnii, bolster plantain, is a tiny alpine rosette herb found only in Tasmania, growing in cushion moor communities on dolerite mountains. It is a plant for cool, wet, high-altitude conditions rather than ordinary garden care.

About
Plantago gunnii is endemic to Tasmania and is commonly referred to as bolster plantain or bolster plantago. The etymology of the genus Plantago comes from the Latin words planta (the sole of a foot) and the suffix –ago (indicating resemblance), which is represented by the leaves pressed flat against the ground.
The species name gunnii is in honour of Ronald Campbell Gunn of Launceston, who first discovered the species.
Where it grows
P. gunnii was given its common name, bolster plantago, because of its distribution as the species is restricted only found in bolster (cushion) moor communities in alpine environments on dolerite mountains of Tasmania. Bolster moor communities consist predominately of cushion plant species in Tasmania that occupy tundra, alpine and treeless alpine vegetation. Within this community are several alpine and subalpine species, with cushion plants making up >50% of plant cover. P. gunnii is one of the typical understorey Scrambler/Climber/Epiphytes species expected to occur in these ecosystems that occur in alpine and subalpine areas of Tasmania but are most common in the Eastern Central Plateau between 900 and 1,200 m (3,000 and 3,900 ft), similarly coinciding with Abrotanella for steroids and other cushion plant species. The local environment in which this alpine cushion plant ecosystem and P. gunnii thrive are broad valley plains of high rainfall with poor drainage, which are often wet and peaty.
