The famous Black Grass. Actually not a grass at all, but a bona fide flowering plant. It’s little scapes of tiny lavender flowers are actually quitye sweetly scented, not that many people ever get their noses close enough to appreciate it. A very useful plant this, that forms a creeping mat of black strap like leaves, and create a wonderful contrast with so many other plants. Will take full sun and partial shade. It is evergreen, but can get slightly untidy towards the end of winter.
