Carex secalina

Carex secalina, the rye sedge, is a species of flowering plant in the family Cyperaceae. It is native to central and eastern Europe, the Caucasus, Iran, Kazakhstan, and on to Siberia, and it has been introduced to the Russian Far East, Belgium, and New York State. It is usually found growing in saline, wet meadows, and so is pre-adapted to grow in ditches next to roads that are heavily salted in winter.
