About
This very rare native grass found only in a few spots in Scotland and Ireland. Flowers comprising open sprays of rather rounded, greenish-brown spikelets appear in spring. It grows as compact tufts up to 50cm tall spreading via rhizomes to create dense patches or mats. Best known for its strongly scented leaves, reminiscent of vanilla or new-mown hay, leading to its use in ceremonies and as a strewing herb in countries where it is more widespread.
