Exotic grass

Juncus effusus grows in large clumps up to about 1.2 metres (3 ft 11 in) tall. The stems are smooth cylinders with light pith filling. The yellowish inflorescence appears to emerge from one side of the stem about 20 centimetres (8 in) from the top. In fact the stem ends there; the top part is the bract, that continues with only a slight colour-band marking it from the stem. The lower leaves are reduced to a brown sheath at the bottom of the stem. It does best in full sun and moost to wet soil
