Holy Basil vs. Basil: Physical Features

Basil physical features

At a glance, you may not be able to tell holy basil apart from sweet basil. However, if you look closely, you will see some noticeable differences. The most striking difference is the texture of their stems. Holy basil has a hairy stem, while regular basil has a smooth, hairless stem. The hairs in holy basil are more pronounced in older plants.

Other differences are in the color, margin, and texture of the basil leaf. Holy basil is light green, while sweet basil is dark green. Holy basil leaves are straight, but those of sweet basil tend to curl downward and inward. The holy basil leaves have tooth-like edges with tiny hairs, while sweet basil leaves have smooth edges with no hair. Also, sweet basil leaves can seem shiny especially when exposed to a lot of light.

Both holy basil and sweet basil produce tubular-shaped flowers, and holy basil produces pink, purple, or white flowers. Sweet basil produces white flowers only.

Holy Basil vs. Basil: The Taste

Holy basil has a peppery, clove-like taste; some people liken its taste to that of Jamaican peppers. Sweet basil has a licorice-clove flavor. The holy basil flavor is more potent than its counterpart. It becomes even stronger when exposed to heat while cooking.

Method of Consumption

We can consume both holy basil and regular basil in a variety of ways. Their leaves and flowers are edible and non-toxic. We can steep them in water to make infused basil tea. We can also infuse the herbs in olive oil or red wine or white wine vinegar to make salad dressings. The leaves or flowers can also be added to salads, to improve flavor, or sprinkled on top for garnish.

Food with fresh herbs on top

People use sweet basil in cooking, for the most part. Because of this, it finds a broader range of applications in different cuisines than holy basil. In most cases, even when people cook with holy basil, it is for its medicinal benefits.

Holy basil is most famous for making holy basil tea. People claim this tea has many health and medicinal attributes. There have been countless studies carried out establishing holy basil’s benefits.

Growing Conditions

Sweet basil is an annual crop. It lasts for a year before flowering, and it seeds towards the end of the year. Holy basil is a perennial crop. It lasts for many years with cycles of dormancy and blooming. It all depends on the weather conditions.

More often than not, holy basil goes dormant in the cold season. During that season, it flowers and seeds, the stems become woody, and they shed its leaves. The plant then enters a growing season in early spring that lasts through the summer.

Holy Basil

During the growing season, it has abundant foliage that you can harvest for use as you please. But in the dormant season, the leaves lose their flavor and may become bitter. So, it is best not to harvest them at that time.

This cycle repeats year after year. If the holy basil plant is in a controlled environment, it does not go into dormancy. You can harvest throughout the year, if the plants are kept in a greenhouse or indoors. Be sure to add compost or organic fertilizer to the soil periodically, to keep the foliage thriving.

Both holy basil and sweet basil depend upon similar conditions for healthy growth. You can propagate them from seeds, cutting, or seedlings. Once planted, they need regular watering. Be sure to water, whenever the first few inches of soil dry up. If growing either type of basil indoors, in dry air, you will need to water up to twice a day.

Holy basil and sweet basil require six to eight hours of daily light to thrive. They can survive in partial sunlight, but they will be less productive. If you are growing them indoors, substitute with grow lights. Generally, they require warm temperatures of 72 to 83 Fahrenheit. They will die or go dormant in cold weather.

Both varieties of basil are prone to pests and disease. These diseases include root rot, mildew, snails, slugs, mites, and fungal infections. To prevent pests and disease, you must maintain sanitary conditions; ensure proper air circulation; and apply an organic pest repellant, such as neem oil.

Basil requires timely pruning to prevent the plant from seeding too soon. As soon as you notice flower buds beginning to emerge, you can pick them. You may use them in your recipes as you would basil leaves. Harvest on demand, but do not harvest more than one-third of the plant at a time.

Nutritional Facts
