The flower bulbs that smell like garlic are Allium bulbs.
Allium: The Garlic-Scented Flower
The Allium genus encompasses a variety of flowering plants, also known as ornamental onions or garlic. These plants are directly related to the onions and garlic that we use in the kitchen. This close relationship is evident not only in their physical characteristics, such as their layered bulb structure, but also in their distinctive scent.
Characteristics of Allium Bulbs:
- Layered Bulbs: Similar to edible onions and garlic, Allium bulbs are made up of layers.
- Distinctive Scent: They emit a characteristic odor that is very similar to the smell of garlic or onion, particularly when the leaves or bulbs are bruised or damaged.
- Variety: Alliums come in a wide variety of shapes, sizes, and colors, making them popular choices for ornamental gardens.
- Ornamental Use: They are primarily grown for their attractive flowers, which can range from small, delicate blooms to large, showy spheres.
Why the Garlic Scent?
The garlic-like odor of Allium bulbs is due to the presence of sulfur compounds, which are also found in onions and garlic. These compounds are released when the plant's cells are damaged, resulting in the characteristic scent.
