Atm thats a tricky subject.
There is the speedgrass included as a single version patch in the demo (with many more in the full version) but this only produces wild-grass variants. The texture resolution is also kind of limited so for close-ups or lawns this is not very well suited.
There have been ideas around to allow for more options but right now, if you want a really good looking grass (as far as mesh based grass will allow for as opposed to displacement grass) you'll have 2 choices:
-Create high-res textures of grass, map them on crossplane-meshes including alpha and import these.
-Create geometry based grassmeshes and import those.
Needless to say the geometry variant will consume tons of polygons and, unless you need it on a very limited area, this is probably the ideal way to kill your memory with great speed.
