The plant reaches a typical height of 12-18 inches (30-45 cm) and emits a distinct onion scent when the leaves are disturbed. The flowers' radiating shape and their dense congregation atop leafless stems make them visually distinctive amidst the plant’s verdant tufts.

Detailed Traits of Wild garlic

Leaf Features

The leaves of wild garlic are 6-12 inches (15-30 cm) long, linear, flat, and semi-upright. They are green and often mistaken for grass when young. Each leaf has a poorly defined keel along its midvein and smooth margins, making them distinctively identifiable. The texture is relatively smooth without any prominent hairiness or serrations. These basal leaves grow directly from the base of the plant, contributing to its characteristic appearance.

Flower Features

Wild garlic produces an inflorescence ending in an umbel of 6 to 12 star-shaped flowers or sessile bulblets, often in combination. The flowers form a dome-like cluster on a naked stalk, each 1/2 inch (1.27 cm) long. They vary in color from pink to whitish. The bulblets are light green to pinkish-red and about 1/4 inch (0.64 cm) long, ovoid in shape. Wild garlic is particularly likely to flower or develop bulblets in sunny conditions.

Stem Features

The stem of wild garlic is terete, meaning it is round in cross-section, and stands stiffly erect. It generally reaches the same height as the leaves or slightly higher, around 1 to 2 feet (30 to 60 cm). The stalk is smooth in texture and unbranched, displaying a consistent green color. This rigidity and form are distinguishing features, aiding in the plant's identification.

Fruit Features

The fruit of wild garlic is a bulbous seed capsule that splits open upon maturation to release several small, glossy dark seeds. These capsules are typically less than 1 inch (2.54 cm) in size. The seeds within have a rigid texture and are shaped to facilitate dispersal by wind or water. The color of the mature fruit ranges from a muted green to brown, harmonizing with the plant's natural habitat and aiding in its camouflage. Its seed capsules are quintessential for species identification among plant enthusiasts.
