Grey Fescue, like an infestation of Star Trek tribbles in your garden.

Festuca glauca, or Blue Fescue, is a wonderful evergreen grass that sports sprays of blue-green leaves and blue-green purple flushed flowers during the summer months. A great choice for a city or cottage garden, and looks fabulous in an informal setting. You can also plant in containers or a rock garden, and it can cope with all that the British weather might throw at it. For those looking for an easy plant to grow, as well as one that requires little on-going care, then this is a great choice. For the best results, plant in a full sunlight position.
