Stylidium, aka trigger plant is a carnivorous plant endemic to Australia.  Part of flowers and stems have sticky glands that capture and digest insects.  The unique feature of this plant is that the flower possesses an appendage consists of female and male sexual organs.  This appendage is set aside when it's ready to pollinate.  When a pollinator visits the flower, this appendage knocks on the back of the pollinator, covering it with pollens, hence promoting cross pollination.  S. productum is a small, fast growing, warm temperate/mediterranean plant endemic to eastern Australia, and can be grown with Sarracenia and Venus flytraps. The plant you will receive is a seedling.
