I've got a friend who studied plant agriculture and farming
at the university and who told me that grass is a rather late
development in the plant kingdom.
Of course I'm aware, that there is grass, thats living more years,
bamboo for example, and one smaller one lives in my garden.
Probably a case of definition: the "grass" thats used here for
cow nutrition will be different.
It lives only one year - same as the food cereals do.
A barley plant lives one year out of one barley corn.

I find this interesting, because such a plant has no interest to
invest any energy in further growth, and will therefore put all
energy into its seed.

Thanks for that information. I'd expect that perennial grasses
were even harder in structure and slower in growth
(but faster, than any other plant after a graze)
