African Basil: A Fragrant Non-Native Herb Worth Considering
If you’re looking to spice up your herb garden with something a little different, African basil (Ocimum gratissimum) might just catch your fancy. This aromatic perennial herb brings a unique twist to the typical basil lineup, though it’s quite different from the sweet basil you might be used to tossing in your pasta sauce.





What Exactly Is African Basil?
African basil is a robust, non-woody perennial herb that’s native to tropical Africa and parts of Asia. Don’t let the name fool you into thinking it’s closely related to your garden-variety sweet basil – while they’re cousins in the mint family, African basil has its own distinct personality. You might also see it listed under its botanical synonym, Ocimum viride, in some older gardening references.
Where Does It Grow?
In the United States, African basil has established itself in Hawaii, where it reproduces naturally in the wild after being introduced. The warm, humid tropical climate of the islands suits this heat-loving herb perfectly.
What Does It Look Like?
This isn’t your dainty herb garden specimen – African basil means business! It grows as a substantial perennial herb with large, fuzzy leaves that release a potent, spicy aroma when crushed. The plant produces attractive spikes of small white or pale purple flowers that add a nice vertical element to the garden. Think of it as the robust, outdoorsy cousin of regular basil.
Should You Grow African Basil?
Here’s where things get interesting. African basil can be a wonderful addition to warm-climate gardens, especially if you’re into cooking with bold, aromatic herbs or want to attract pollinators. The flowers are quite popular with bees and butterflies, making it a functional choice for pollinator gardens.
However, since it’s not native to most areas where it’s grown, you might want to consider native alternatives that provide similar benefits to local ecosystems. Native herbs and flowering plants often offer better support for local wildlife while still giving you those aromatic and aesthetic qualities you’re after.
Perfect Growing Conditions
If you decide to give African basil a try, here’s what it needs to thrive:
- Climate: USDA zones 9-11 (it’s definitely not frost-hardy!)
- Sunlight: Full sun to partial shade
- Soil: Well-draining soil that doesn’t get waterlogged
- Water: Regular watering, especially during dry spells
- Temperature: Loves warm, humid conditions
Planting and Care Tips
Growing African basil successfully is pretty straightforward if you can provide the right conditions:
- Start from seeds or cuttings in spring after all danger of frost has passed
- Space plants adequately as they can get quite bushy
- Pinch off flower spikes if you want to encourage more leaf growth
- Harvest leaves regularly to keep the plant productive
- In cooler zones, grow it as an annual or bring potted plants indoors for winter
- Consider container growing if you’re outside its comfort zone climatically
Garden Design Ideas
African basil works well in several garden settings:
- Herb gardens where you want something with serious aromatic punch
- Tropical or warm-climate landscapes as a textural element
- Container gardens on patios or decks
- Pollinator gardens where its flowers can do double duty
- Kitchen gardens for adventurous cooks
The Bottom Line
African basil can be a rewarding plant to grow if you’re in the right climate and looking for something a bit different in your herb collection. Its robust nature, attractive flowers, and pollinator appeal make it a functional choice. Just remember that supporting native plant communities is always beneficial for local ecosystems, so consider exploring native aromatic herbs and pollinator plants for your area as well. Whether you choose African basil or native alternatives, you’re sure to create a garden that’s both beautiful and beneficial!
