I have many kinds of miscanthus, and some are very slow growing (Strictus, but worth it) or don't flower for several years (Monring Light, but worth it). I remember that this grass jumped out of the ground and grew really big really fast and then widened.
According to my records, I planted it in fall of 2004. Here is is in August of 2007 - the first picture I have of it. Three years later. And as you can see from the picture, it was already quite mature by the time I photographed it.
So, as you can see, it doesn't waste any time! It is particularly happy if you plant it where a bit of water drains toward it. Other than that, I never did anything but cut it down in April, and give it a little 10-10-10 fertilizer (and I stopped doing that, because it didn't need it).
Please see below for the August of 2007 pic. I didn't include it here.
It's a glorious grass. Do enjoy it!
I got my start in 1998, at Milaegers in Racine. I had moved into my new home in July, and it was former farmland, so I installed everything. I did get a landscape plan, and wanted LOTS of grasses. It was fall, a supposedly risky time to plant grasses. So they were conducting the following promotion:
Buy 12, get 6 free
Buy 6, get 3 free
Buy 3, get 1 free
I was shameless, and made multiple trips even though they were 45 miles away (ah, I remember 99 cent gas!)
They still smile when they see me. And I figured out that I paid an average of $2.50 for each grass.
Watch out for fall sale grasses! Cut all the flowers off (when they are flowering, they are spent, like any other perennial) but if you want a lot, that's the time!
Thank you very much for the photos and info. We bought an older home and property with a sorely neglected yard. I'm starting from scratch except for the trees and a row of Azaleas across the front of the house. In the back, I want to use the tall grasses extensively.
I have purchased a number of types of grasses already, and I am going to look for Miscanthus giganteus as soon as I can. I'm hoping to find it locally. ♥
When I have cut it back in the spring i have found the stems very thick for a miscanthus of any kind - yet they are light because many of them are hollow. They don't fall apart, but I suspect that they would possibly be too light to be substantial enough for your task.
