I learned about Miscanthus earlier this year and became very excited about the prospective of using it to grow my own mulch (versus importing woodchips). I have a 5 acre berry orchard so I can't rely solely on the occasional free shipment of chips. I also plan to use it as bedding for my horses (and in turn great
compost).
I'm in Zone 4 so cooler than the traditional growing habitat of this plant. I bought and planted about 1/10th of an acre this spring of a sterile variety bred for biomass production. I planted in June and they grew about 2.5 feet in the first season. The big test will be this winter to see if they can survive the deep freeze in this area. If they do I plan expanding much larger by dividing the rootballs. Assuming it works, I'll have a locally available starting source for others in the area.
It seems an ideal plant to have as mitigation for climate change; as it's heat loving and water efficient.
