Festuca heterophylla, the various-leaved fescue, is a species of perennial plant from family Poaceae that is native to southern Europe. It is also grows in Asia, and in such US states as New York and Virginia.
It has a Eurosiberian distribution. In Spain it is found in Barcelona, Gerona and Lérida, in humid and shady forests (generally beech, fir or red pine forests).
It is a herbaceous plant that belongs to the genus Festuca, undoubtedly the most complicated among the grasses. However, this species is easy to distinguish, due to its marked foliar dimorphism: the basal (lower) leaves are more or less capillary (quadrangular in section), while the caulinar (upper) leaves are flat (2 to 3 mm in length. width).

How to get rid of:
It is often more effective with tall herbaceous plants, such as
grasses, and some woody weeds to first slash the area and only
spray the re-growth. Allow 3–4 weeks for new lush growth and
then spray. Most chemicals works best when plants are healthy
and actively growing. By removing dry stems and forcing the plant
to put on new growth the uptake of herbicide will be improved.
This method has the added benefit of opening up the space and
improving access, and can result in less herbicide being used.
