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.

Once you have found the plant that looks right for you, the next step is where to buy it.
Most nurseries stock a good range of plants, but due to space and supplies, they may not always have the plant that you are searching for in stock. If they don’t, they may be able to order it in for you if you request it.
