Miscanthus plants are native to China and Japan. They go by the common names Chinese silvergrass, Suzuki grass, Porcupine grass and Maiden grass. They are a great plant to use for providing the often forgotten element of movement in your garden as the flower heads sway around in the breeze when the wind picks up. They are sometimes recommended as a plant for prarie style gardens. They also look stunning with the sun shining behind the flower heads. They can be propagated by division. They respond well after transplanting and you don't have to be overly careful after pulling them up. Digging the plant out of the ground is the hardest part. They have a dense fibrous root system that needs to be dug around and under to lift the plant. I would describe their water usage as low / medium once established.
When I first started working in the Parkville garden where I currently am employed, we dug up a mature Miscanthus transmorrisonensis plant and divided it into about 8 clumps. What you see in the pictures below is 6 of those clumps approximately 1 year after planting them. They are about 1.2 metres tall.
Here it is in all its glory. Honestly it looks significantly better in real life when it is swaying around in the wind with the sun shining on it.
