I found it by searching for "specialist grass nursery", I found one with a long list but only a few links to a photo so I started to search for each genus. That brought me to the hlasek site which has a lot of European bugs and plants, I then went to the galleries and looked in Juncales. That's how I found it by going through the list! Most grasses are native, the two I have are native to here which I didn't know.
