Am I missing something? Grilled an artichoke today but the only part that seemed edible was the very inner?

bottom core? The leaves while wilted and easily falling off the artichoke, they seemed inedible I followed directions from a blog on how to cook it, but is that all there is to eat? That little at the bottom? It was nice and soft, but just seemed like I'd need to buy at least 3 for just myself!
