Stylidium graminifolium, the grass triggerplant, is a carnivorous perennial plant with grass-like leaves and is easily cultivated. It possesses glandular trichomes underneath the flowers that can trap and digest prey.

This species is an erect perennial herb with 5–40 cm (2–8 in) long narrow, grass-like leaves. A 15–90 cm (6–36 in) long scape bearing pink butterfly-shaped flowers appear in the spring and summer (October through February), and are quite showy! This species, like most Stylidium species, possesses glandular trichomes underneath the flower and on the scape, which are capable of digesting and absorbing nutrients from prey captured in the sticky mucilage. This information leads some researchers to believe that the plants are carnivorous or at the very least protocarnivorous.

S. graminifolium has one of the widest ranges in the genus Stylidium, extending from Tasmania to Victoria, New South Wales, and Queensland over to South Australia. Its most common habitat is dry sclerophyll forests with nutrient-poor soil conditions.

Hardiness zones: 8-11

Seeds per pack: 3

Type: Tropical or houseplant

Germination: Unlike most carnivorous plants, the trigger plant can handle nutrients in the soil.  Sow seeds onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. Germinate at 15 to 20 degrees C. Seeds germinate in 2-10 weeks although they make take considerably longer and have been known to take up to a few months. They are worth the wait!
