Growing Purple Basil: A Fragrant and Ornamental Herb

Purple basil, also known as purple ruffles basil, is a popular plant among garden enthusiasts. With its beautiful leaves and fragrant aroma, it not only adds a touch of color to your garden but also enhances the flavor of various dishes. In this article, we will delve into the world of purple basil and explore how to grow it successfully.


Purple basil, scientifically known as Ocimum basilicum, is an annual plant that belongs to the mint family, Lamiaceae. It is primarily cultivated for its ornamental purposes due to the striking purple color of its leaves. However, it is also edible and offers a unique flavor to culinary creations. Whether you are a seasoned gardener or a beginner, growing purple basil can be a rewarding experience. Let's dive into the details and learn how to grow this versatile herb.

Overview of Purple Basil

Purple basil comes in various cultivars, each with its unique traits and appearances. While the name "purple basil" has been used interchangeably for multiple cultivars, it generally refers to varieties that display vibrant purple foliage. Some cultivars may have leaves that are completely purple, while others exhibit a combination of green and purple hues. The intensity of the purple color can vary depending on the cultivar and environmental factors.

Growing Purple Basil

3.1 Planting Season

The best time to plant purple basil is during the spring season, particularly in regions with a hot climate. However, it can also thrive in tropical, subtropical, temperate, and even desert climates as long as the winters are not extremely cold. In desert regions, providing partial shade to the plant can help protect the leaves from scorching.

3.2 Sunlight Requirements

Purple basil thrives in full sunlight. It requires at least 6-8 hours of direct sunlight per day for optimal growth. However, in extremely hot climates, it is advisable to reduce the amount of sunlight the plant receives to prevent the leaves from wilting or getting scorched. Providing some shade during the hottest part of the day can help maintain the health of the plant.

3.3 Watering and Moisture

Purple basil prefers moist soil conditions. It is crucial to keep the soil consistently moist, especially during hot summer days. However, it is equally important not to overwater the plant as excessive moisture can lead to root rot or fungal diseases. Regular watering and monitoring the soil moisture levels will ensure the plant thrives without any issues.

3.4 Propagation Methods

You can grow purple basil from seeds, cuttings, or planting nursery-bought plants. While growing from seeds can be a rewarding experience, it is worth noting that purple basil seeds are more sensitive compared to other basil varieties. Ensure that the seeds are fresh, as older seeds might have lower germination rates. Alternately, you can take cuttings from an existing plant and root them in water. This method allows you to propagate multiple plants from a single parent plant.

Pests and Diseases

4.1 Common Pests

Just like other basil varieties, purple basil is susceptible to certain pests. Slugs, aphids, grasshoppers, and snails are some common pests that can affect the plant's health. These pests can cause damage by feeding on the leaves and stems, leading to stunted growth or even death of the plant.

4.2 Pest Control Measures

To control pests, various methods can be employed. Manual removal of pests, applying insecticidal soaps or oils, and using natural predators like ladybugs can help maintain a healthy plant. Additionally, practicing proper garden hygiene, such as removing weeds and debris, can prevent pests from thriving in your garden.

4.3 Common Diseases

Purple basil is vulnerable to fungal and bacterial diseases, including Fusarium wilt, downy mildew, and bacterial leaf spot. These diseases can cause discoloration, wilting, and overall decline of the plant's health if left untreated.

4.4 Disease Prevention and Treatment

To prevent diseases, ensure good air circulation around the plant and avoid overhead watering. Watering at the base of the plant and using well-draining soil can help prevent fungal growth. If signs of disease appear, promptly remove the affected plant parts and apply appropriate organic or chemical treatments to control the spread.

Plant Size and Growth

Purple basil typically reaches a height of 20 to 40 centimeters (8 to 16 inches). However, with optimal growing conditions and proper care, the plant can grow taller. Regular pruning and pinching back the stems can encourage bushier growth and prevent the plant from becoming leggy.

Harvesting Purple Basil

The timing of harvesting is crucial to maximize the flavor and prolong the lifespan of purple basil plants. It is recommended to harvest the leaves and stems when the plant is well-established. By harvesting only the leaves and leaving some stems intact, you can ensure continuous growth and availability of fresh basil leaves throughout the season. Additionally, harvesting stimulates the plant to produce more foliage, resulting in a healthier plant overall.

Culinary Uses of Purple Basil

7.1 Salad

Purple basil leaves can be used to add a pop of color and flavor to various salad recipes. Whether used as a garnish or mixed into the salad, purple basil leaves provide a distinct earthy and slightly spicy taste that complements a wide range of ingredients.

7.2 Spices

Dried purple basil leaves can be ground into a fine powder and used as a spice in a variety of dishes. It imparts a unique flavor to soups, stews, marinades, and stir-fries, adding depth and complexity to the overall taste.

7.3 Pesto

One of the most popular culinary uses of purple basil is in pesto sauce. By combining purple basil leaves, garlic, pine nuts, Parmesan cheese, and olive oil, you can create a vibrant and flavorful sauce that pairs well with pasta, bread, and even grilled meats.

Other Varieties of Basil

Apart from purple basil, there are numerous other basil varieties that offer different flavors and appearances. Some popular varieties include sweet basil, Thai basil, lemon basil, and holy basil. Each of these varieties has its unique characteristics and uses in the culinary world.
