Bossy Grass Cage Match!

I'm planting 2 kinds of VERY bossy grasses in a small, built-in planter box in my front yard...

Which do you think will win?

I think the Elymus 'Blue Dune' will, because it's stronger and more boisterous than the Jersey Shore kids.

But Imperata cylindrica 'Red Baron' runs like a pair of cheap panty hose...

What do you think?
