Got more info on it:

Its Amerika-agave (Agave americana) is in the family of asparagus plant.

It is a perennial herb with a flower stem up to 7 m high. The leaves sit in a rosette at the margin or on a short stem. The grey-green or blue-green leaves are spear-shaped, 80–200 cm long and 15–25 cm wide. They have a sharp, black thorn at the end, and the leaf margin also has thorns.

And as it happens, I've got that in one of my X-Frog collections.  It's flowering but can hide the blooms, And it will be instanced so I can control where and primarily to break up the horizon.

But I do like your suggestion. ;)
