WHAT AM I?

I was wandering around downtown yesterday when something in the little flowerbed near Ino'z stopped me in my tracks. I've passed it a million times before, and recognize most of the plants there, but these little grassy clumps had a surprise up their sleeves! Instead of sending up the usual light, feathery plume, they are sprouting these gorgeous-ginormous seedpod thingamabobs that are just begging me to find a place for them in the Cantina Garden. 

So, I've got to know. What IS this fantabulous plant?
