Floor Vase

What size floor vase would I need for grasses that are 120cm tall?

We have some wheat, about the same size as yours, in a floor-standing vase, . Wheat has a pretty rigid stem and the vase is about half the height of the wheat. Floppy grass might need a taller vase.

This links shows 140cm pampas grass in a floor standing vase and therefore might give you an idea of what you should be looking for:

This image seems to be the one above but zoomed out a bit, possibly offering you a clearer view: https://i.pinimg.com/originals/5b/ea/9a/5bea9a1394ff0865b5c7845362872b63.jpg

Whatever you decide to opt for, I'd suggest that the base needs to be broad enough for the grasses to stand up on their own, without needing the help of a nearby wall for support (or to prevent the vase being knocked over). This simply doesn't look good to me:
