The differences in broadleaf weeds' structure and growth habits make them easy to distinguish from narrow-leaved weedy grasses. [5] Most broadleaf weeds have leaves with net-like veins and nodes that contain one or more leaves, and they may have showy flowers, [6] while grassy weeds appear as a single leaf from a germinated seed.
