When the pink flowers are gently prodded, the style suddenly flips over. This was used as a source of amusement.


Trigger Plant is widespread in red gum woodland, plains grassland, dry and valley sclerophyll forests and grassy open forests. It is found in Victoria, Queensland, New South Wales, Tasmania and South Australia.


In cultivation this tufted perennial can vary in size and will tolerate wet and dry conditions once established. It prefers moist well drained soils in sun or part shade. In the wild, it grows to 20–60 cm tall and 20–30 cm wide.
