Very beautiful (evergreen foliage and very blue!)
Blue fescue is an interesting herb because it is evergreen and very blue (mine are at the moment, and they have withstood the winter well, even though they were rather green when I received them).
Some advice:
> Mulch them well at the base (do not plant them among other herbs, which will "eat" them very quickly).
> All exposures are suitable for them.
> Another piece of advice: DO NOT PRUNE THEM SHORT like Miscanthus, otherwise you risk killing them. Indeed, these herbs, unlike Miscanthus (Chinese reed), are EVERGREEN; so it is enough to "clean" them in spring (just remove the dead parts). The fact that these herbs are evergreen is also an excellent asset if you want a colourful garden even in winter. You can also associate them with other colourful evergreen foliage such as the red-orange foliage of nandina domestica (varieties "Gulf Stream" for orange and "Obsessed Seika" for red), and the bright tones of lonicera nitida (boxleaf honeysuckle) "Baggesen's Gold" and "Lemon Beauty". You can also add a mahonia Media "Charity", for the magnificent shape of its shiny leaves, very original (which can be kept small by pruning, or allowed to grow, but it takes up space), and a pyracantha (the "Saphyr" varieties are resistant to fire blight), which will dazzle you in May with its myriad of small immaculate white flowers, followed by magnificent red, orange or yellow berries, which you can admire in autumn and also part of the winter. Such an association (like the one I have in my own flower beds, for evergreen plants) will produce a stunning effect, in addition to requiring zero maintenance in the long run (all these plants being practically "indestructible", as well as beautiful). Finally, dwarf varieties of abelia (semi-evergreen) will add the finishing touch! You can also opt for the different varieties of Berberis Thunbergii (you can find all the shapes and colours you want), which keep their foliage for a very long time and, as a result, can almost be considered as semi-evergreen. For a beautiful contrast effect, I recommend the following varieties: "Orange Rocket", or the smaller variety, "Orange Ice" (almost fluorescent all season), "Golden Torch" (a yellow flame, then orange in autumn, which does not burn in the sun), or "Golden Carpet" depending on the shape you desire, or "Diabolicum" (always in yellow tones, marbled with orange as a bonus). The variety "Harlequin", on the other hand, turns pink in summer. Finally, the variety "Atropurpurea" remains burgundy (then red in autumn). Unfortunately, too many French gardeners ignore these plants because of their thorns, even though they are, in my opinion, MUCH MORE BEAUTIFUL than many roses, which are also very thorny, in the sense that their evolving colours will enchant you throughout the season and offer a spectacle just as striking as flowers, but with the advantage of lasting much longer...
