Grass in winter

[Guinan]

I just discover many things since the update and today I saw grass in winter for the first time. I love it because it looks sooo beautiful.
My question is if I can make hay of this winter grass. In the Wiki I do not find anything about it. Is it a bug or did nobody write about it until now?
Does it grow? On another farm I have I did not see it but I already was in winter when the update came out.
This is one of my favourite things from the update.

Thank you.
I think my silo was full but I will only make hay when I do not have anything because it really looks beautiful.

No it does not grow

Yes it can be cut into hay, but not as effectively. This is in the wiki, but the particulars are vague:

The best part of this is Grass will continue to spread the following Spring and beyond so you don't lose your Grass investment over Winter. And like when you plant Grass Starters on Winter 28, the existing Grass will do the same huge Grass explosion on Spring 1.
