The Story

Blue Lyme Grass, a.k.a. Blue Rye Grass, brings a breezy, beachy feel to the landscape, as this is one of the Fringes that grow naturally by the seashore. It’s found near the Atlantic Ocean, on the coasts of the British Isles and western and northern Europe. With its thick mass of roots, Blue Lyme Grass helps keep the sandy shoreline from disappearing into the ocean, while its frosty blue blades make a pretty display. Blue Lyme Grass is native to northern regions, and therefore it possesses excellent cold hardiness. Blue Dune is a special selection that tolerates high heat and humidity as well.

The Details

Although Blue Lyme Grass likes to grow by the seashore, that doesn’t mean it likes to be in the water. Blue Dune is a rugged Fringe for average to dry soils. It will perform like a champ in any well-drained site and is valued for its drought resistance.

How to Grow

Plant fast-growing Blue Dune Lyme Grass in a sunny or lightly shaded spot where it has room to run. This is a cool season grower, which means that new leaves emerge early in spring, when many other Fringes are still dormant. If the foliage looks tired in summer, you can easily mow it down and it will send up fresh blue blades. Cut back old foliage in late winter to make way for the new. Blue Lyme Grass has become invasive in the Wisconsin counties bordering Lake Michigan, and it shouldn’t be planted there.
