Stanmore, Middlesex, United Kingdom

dDoes anyone know what species + variety of grass this is?

It grows to about 6' in a good year, presumably depending on the spring rain. (It's definitely taller this year!) After it flowers in mid-late June, the flower heads gradually close. By mid-Aug the thin tubular stems have turned brown. It stays like that through the winter.
