Please help identify these bushes

If your talking about the tall grass like stuff, it looks like day lilies. They're bulbs and can be dug up & divided individually or in clumps. You can use an axe or hatchet to divide them or soak them in water and pull them apart, depending on how much time you want to spend. Looks like you have a good amount there. They like full sun and are pretty tolerant. If you have a path you could line them down it. I have them lining up my driveway. They flower once a year unless you get the re-blooming ones, which I doubt these are because the greenery stays a little more dwarf size & compact. The individual flowers once opened last one day, hence the name day lily. =)
