Lolium perenne

Perennial ryegrass

Turf-Type tetraploid Perennial Ryegrass

Looking for oustanding colour?

TETRADARK is the darkest material ever released from DLF to date. This tetraploid is a unique deep dark green. It really stands out.

Excellent disease tolerance and winter performance

TETRADARK has the already known and loved advantages of DLFs 4turf: improved disease resistance especillay for red thread and dollar spot. It has high lawn quality in winter, fast germination, a long growing season and a good regrowth in spring.


TETRADARK has moderate density enabling it to blend better with turf-type tall fescue, Kentucky bluegrass, diploid perennial ryegrass and fine fescues.

Use TETRADARK in an overseeding mixture to obtain that healthy looking well-nourished lawn cover. Or perhaps as a contrast for lawn design and pattern making.   

The shade of the grass is genetic and does not fade like pigmented lawn.
