Lemon basil is a fragrant herb with soft green leaves that release a bright citrusy scent when rubbed or crushed. The fragrance is fresh and uplifting, making it widely used in cooking, herbal teas, and for flavouring drinks.
If you enjoy using fresh herbs from your garden, lemon basil is one you can start growing and adding to your collection.
In this guide, I will show you how to grow lemon basil in containers and how to use it in everyday life.
What is Lemon Basil?
Lemon basil is an aromatic herb in the mint family, Lamiaceae, native to tropical and warm temperate climates. It is known botanically as Ocimum × africanum. The “×” symbol indicates that it is a natural hybrid, resulting from a cross between sweet basil (Ocimum basilicum) and a wild basil species (Ocimum americanum).
Lemon basil is easy to recognise once you look closely.
- Growth habit: Grows upright and becomes bushy, branching freely into a full plant
- Stems: Slightly square, not round, typical of the mint family
- Leaves: Smooth, oval to slightly pointed, light green, with a soft texture
- Leaf arrangement: Leaves grow in opposite pairs along the stem
- Flowers: Upright spikes with small white, tubular, two-lipped flowers arranged in rings along the stem; seeds form within the dried flower structure
- Height: Under favourable conditions, it can grow up to 50cm before flowering
How to Grow Lemon Basil in Containers
Lemon basil can be grown directly in the ground in tropical gardens, but it is also easy to grow it in containers. If your outdoor space is mostly concrete (like mine), growing it in pots makes it much easier to manage and move around as needed.
Sunlight
Lemon basil grows best outdoors. A sunny spot where the plant receives morning or afternoon sun works well. If the sun is very harsh, especially in the dry season, a little shade later in the day can help prevent stress.
Water
Lemon basil likes consistent moisture and grows especially well during the rainy season.
In the dry season, you will need to water more often to keep the soil evenly moist. The goal is to keep the soil from drying out completely, while also avoiding waterlogging. If the soil stays too dry for too long, the plant may become stressed and stop growing well.
Soil
Use rich, well-draining garden soil. A loose, fertile mix allows the roots to grow easily and supports steady growth. If your soil is heavy, you can improve it by adding organic matter to help loosen it.
It’s possible to grow lemon basil in heavy clayey soil, though, but there’s an art to it that I have not quite mastered.
Pots
Choose a pot with good drainage, and one that is large enough to support the plant as it grows. A container that measures up to 30cm in diameter (for a round one) or on both sides (for a square or rectangular one) is a good size to grow the plant to maturity. It should be at least 25 cm deep as well.
The material may be plastic or clay. Clay pots are porous and would allow the soil to dry out more quickly than plastic pots would.
Grow bags are also great for herbs. They are made from a breathable fabric material that allows air and water to pass through, helping the roots grow more naturally. They work well as an alternative to pots for container gardening in small spaces.
How to Propagate Lemon Basil
Lemon basil is easy to multiply from seeds and from stem cuttings.
From stem cuttings
- Cut a healthy stem just below a node
- Take off a few lower leaves and any flower spikes
- Place it in water or moist soil and protect it from direct sunlight
- Roots usually form within one to two weeks
From seeds
- Sow lightly on the soil surface
- Keep moist until germination
- Seeds sprout readily in warm weather
If you already have one plant, cuttings are the quickest way to make more.
How to Harvest and Prune Lemon Basil
- Pinch the tips regularly to encourage branching
- Harvest leaves often to keep the plant productive
- Remove flower spikes if you want to prolong leaf production
Frequent harvesting keeps the plant bushy and delays flowering. Once the plant flowers, it stops producing new leaves as it spends all its energy on preparing seeds for the next generation.
The small, white flowers are edible as well. They have a sweet lemon flavour. You can harvest some flowers to use and leave others on the plant if you want it to produce seeds.
How to Use Lemon Basil at Home
Like other basil varieties, lemon basil contains beneficial plant compounds, including essential oils and antioxidants. Research on basil (Ocimum species) shows that these compounds contribute to antioxidant and anti-inflammatory effects, which support overall well-being.
In everyday use, it is best enjoyed as a flavourful, refreshing herb that adds both taste and light nutritional value to food and drinks. Use it to flavour sauces, stir-fries, and marinades and also consume raw in salads. Infuse fresh leaves in boiling water to make a fragrant herbal tea, or add to cold water and homemade drinks for a fresh citrusy note.
Freshen rooms with lemon basil stems and flowers in floral arrangements. You can also squeeze some fresh leaves and apply the extract on your skin as a safe insect repellent.
Finally…
Lemon basil is a rewarding plant to grow. Brush past it, and you catch a fresh citrusy scent. Prune it, and it grows fuller. Harvest it and use it in different ways. It has certainly earned its place in my garden. I hope it can find a place in yours, too.
