If your garlicky stuff is growing in grass, it could be crow garlic, Allium vineale, which has fairly tall wiry stems, bulbils as well as flowers and a few leaves that look a bit like chives. In the US it's an invader from this side of the pond. You can use it like garlic, but it's a tough old thing and the flavour and smell is very strong and unsubtle. If it gets into pasture and is grazed by animals, the meat and milk takes on a disagreeable garlic whiff. If it grows in grain crops and is harvested with the grain, the same taint happens. It's not my favourite plant.
