Brussel sprout cross-section. If you slice a brussels sprout in half, you'll see concentric rings that look almost exactly like a tiny cabbage or tree rings, because the leaves literally spiral inward from the outside as the plant grows. These rings aren't just for show either—they're an edible record of the sprout's growth, with the outer leaves being older and often more bitter than the tender, sweeter leaves toward the center.
