Fennel seeds (Foeniculum vulgare) are a widely used spice known for their sweet, licorice-like flavor and health benefits. Whether you are cooking, making herbal teas, or exploring natural remedies, understanding what fennel seeds look like can help you identify quality seeds and use them effectively.
Fennel seeds are small but distinct, with a unique shape and color that make them easily recognizable in both culinary and herbal contexts.
Physical Appearance of Fennel Seeds
Fennel seeds are small, oval, and slightly curved. Their texture is firm and dry, with a smooth surface. They are usually greenish to pale brown, depending on the variety and drying process.
Key visual features:
- Size: Approximately 4–10 mm in length
- Shape: Oval, slightly curved, with fine ridges running along the length
- Color: Greenish when fresh, turning light brown after drying
- Surface: Smooth with longitudinal lines
- Aroma: Sweet and mildly licorice-like, which helps distinguish them from similar seeds
These physical characteristics make fennel seeds easy to identify compared to other spices like anise or caraway seeds, which may look similar but differ in size, shape, and flavor.

Different Forms of Fennel Seeds
Fennel seeds are available in several forms, each slightly different in appearance:
- Whole Seeds: Oval, smooth, and slightly curved. These are most common in cooking and teas.
- Crushed Seeds: Coarsely crushed seeds retain the color but release more flavor and aroma.
- Ground Fennel: Powdered fennel is light green to brown and is used in spice mixes or baked goods.
- Fennel Tea: Steeping whole seeds in hot water softens them, but their shape remains recognizable if strained.
Tips for Choosing Quality Fennel Seeds
When buying fennel seeds, look for:
- Color: Greenish to pale brown; avoid overly dark or discolored seeds.
- Aroma: Fresh fennel seeds have a sweet, licorice-like fragrance.
