Carex echinata Star Sedge CC DD N
When starting to try to identify sedges it's a good idea to look for those with distinctive features. This is such a sedge. Only small, hardly ever much more than 30 cm tall, this rather attractive little sedge grows in acid or neutral boggy areas and the fruits do look star shaped as the name suggests.
It is very common in the west of Great Britain, western Wales and the whole of Ireland but records are fewer in the east and east midlands of England.
