Looks like the wild garlic that is endemic in my area. Are you sure it doesn't grow taller and flower? Maybe later in the season? Down here where the growing season is farther along, the wild garlic in my
yard is at the flower bud stage. The flowers are never very big or showy, and by mid summer they will have a cluster of little bulblets at the top of the stalk. When you crush the bulblets, you get the unmistakable smell of garlic, but since they are smaller than a peppercorn, they are hardly worth the trouble.
