Stylidium graminifolium, commonly known as Grass Triggerplant, is a perennial herb endemic to Australia, characterized by its grass-like leaves that form a basal rosette. This species is notable for its unique pollination mechanism involving a sensitive floral column that triggers when visited by an insect, ensuring cross-pollination. Grass Triggerplant reaches up to 35 inches in height and blooms from October to February, showcasing pink butterfly-shaped flowers that are both intriguing and attractive to pollinators. It is native to dry sclerophyll forests and heathlands, often found on nutrient-poor, well-drained sandy or rocky soils in Tasmania, Victoria, New South Wales, Queensland, and South Australia.

Grass Triggerplant is valued for its ornamental features and resilience. It is hardy in USDA zones down to -10°C, making it suitable for a variety of garden settings. Cultivars like ’Tiny Trina’ and ’Little Sapphire’ offer gardeners distinctive foliage and flower colors, enhancing the plant’s appeal. In cultivation, it requires minimal maintenance, thriving in full sun to part shade and tolerating drought once established. While it is not commonly used for culinary or medicinal purposes, its unique pollination strategy and the presence of trigger flowers make it a fascinating subject for educational gardens and native plant enthusiasts. Potential problems include root rot in poorly drained soils and susceptibility to snails and slugs.CC BY-SA 4.0
