You get little, white flowers not much bigger than these seed heads, here. And then the leaves are very desert-like. They look like the leaves of yuccas. And sea holly, too, I believe. Sea holly in your garden.
People are probably more familiar with that one.
You've got some others that have some neat history to them compassplant, for instance. The kids think that they look that big. But they also want to know why it's called compassplant. Because you can tell direction with the leaves. The leaves point in a north-south direction.
