The Many Names for Scent Leaf
Scent leaf, a fragrant and flavorful herb, is known by several names depending on the region and the specific botanical variety. Its scientific name is Ocimum gratissimum, and understanding these different labels can help you better identify and source this versatile plant.
African Basil
This is one of the most common and widely used alternative names, especially within West African communities and international markets. The name reflects its strong ties to African cuisine and traditional practices, where it is a staple ingredient. It is also sometimes known as wild basil, particularly in places where it has become naturalized, like Hawaii.
Clove Basil
Another frequent name for scent leaf is clove basil. This moniker is a direct reference to the herb's unique aroma, which carries a distinct spicy scent reminiscent of cloves. This spicy and warm fragrance makes it a valuable culinary herb, though it is generally used more sparingly than milder basil varieties.
Regional Nigerian Names
In Nigeria, a country where scent leaf is integral to many traditional dishes, the herb is known by a variety of local names based on regional dialects:
- Efirin: The name used by the Yoruba people in Southwestern Nigeria.
- Nchanwu / Nchuanwu: The name used by the Igbo people in Southeastern Nigeria.
- Daidoya: The name used by the Hausa people in Northern Nigeria.
Other African dialects also have their own names, reflecting the plant's widespread use across the continent. Some variations of holy basil (Ocimum tenuiflorum) are also sometimes called scent leaf, but Ocimum gratissimum is the primary species associated with the name in African contexts.
Scent Leaf vs. Other Basil Varieties
While scent leaf belongs to the same plant family as other basils (Lamiaceae), its flavor profile and characteristics are distinct. It's important not to confuse it with common sweet basil (Ocimum basilicum) or even other forms of holy basil (Tulsi), as their tastes and applications differ.

How to Grow and Identify Scent Leaf
Identifying scent leaf is relatively straightforward due to its distinct features. For those interested in home gardening, it is also a rewarding plant to cultivate.
Identification Tips:
- Scent: The most prominent feature is its strong, minty, clove-like aroma, which becomes more pronounced when the leaves are crushed.
- Leaves: The leaves are typically ovate with serrated, or sometimes wavy, edges and a somewhat fuzzy texture. They are arranged in opposite pairs on the stem.
- Stem and Flowers: The stem is often round and quadrangular, woody at the base, and branched. It produces small, white or pale yellow flowers in terminal spikes.
Cultivation Tips: Scent leaf can be grown from either seeds or stem cuttings. It thrives in warm, tropical, and subtropical climates but can be grown as an annual in cooler regions. It requires full sun exposure and well-draining soil. For propagation from seeds, simply sprinkle them on the soil surface, as they require sunlight to germinate.
