Triodia scariosa -Porcupine Grass

An interesting tussock forming perennial from inland areas of Australia, worth planting in larger gardens and landscaping for a real wow factor. Growth is by creeping stolons, and older clumps form eye catching ring shapes up to 3 metres wide. This can be replicated in shorter time by arranging small plant clumps into the desired shapes. Spectacular in flower when the name ‘porcupine grass’ really comes into play, though this could also reflect the irritating nature of the seeds heads! Flowering is after rain, generally spring and summer. Naturally occurring in clay and alkaline soils in arid and semi arid areas. Propagation is by division of the clumps. A good shelter plant for small mammals, birds and lizards with its dense habit, which also makes it a great plant to combat soil erosion.
