These steps should get you started. This should at least get the grass growing from the ground. You can also go into edit mode and rotate the strands that way.

Load up the file.

Select one of the strands.

Go into edit mode.

Select the bottom three vertices.
Shift s > cursor to selected.

Leave edit mode.

Right click.
Set Origin > Origin to 3D Cursor

Select the ground plane.
Shift s > Cursor to Selected

Select the strand.
Shift s > Selection to 3D Cursor
