Revered as an ‘elixir of life’, Ocimum sanctum (Holy Basil) is an erect, many-branched subshrub in tropical climates, often grown as an annual elsewhere. It boasts green or purple, smooth elliptic leaves and spikes of small, white or mauve flowers arranged in close whorls on dark stems. Holy Basil is grown for both ornamental and therapeutic uses. Native to India, it has been adopted into spiritual rituals and lifestyle practices. Considered a sacred plant by the Hindus, it is often planted around Hindu shrines. It is used in Ayurvedic medicine as an adaptogen to counter life’s stresses. Its daily consumption would prevent disease, promote general health, well-being and longevity and assist in dealing with the stresses of daily life. But there is limited scientific research to support these benefits yet. A soothing tea is made from the leaves, fresh or dry. Holy Basil is often added to stir-fry dishes and spicy soups because of its peppery taste.

  • Grows up to 24 in. tall and wide (60 cm).
  • Performs best in light, well-drained, fertile soil in a sheltered position in full sun. Water freely in summer. Basil is extremely frost sensitive.
  • Harvest mature leaves for fresh use at any time.
  • Although Basil naturally repels mosquitoes and flies, it attracts bees, butterflies, and other beneficial insects to the garden.
  • Basil is a valuable addition to the vegetable garden and an excellent companion plant for tomatoes, peppers, parsley, lettuce, asparagus, beans, beets, cabbage, eggplant, marigolds, potatoes, or oregano. Avoid planting Basil near Rue (Ruta graveolens) and Sage (Salvia officinalis).
  • While Basil makes a colorful and flavorful addition to many dishes, it can also provide some health benefits. Basil contains many vitamins and minerals, as well as antioxidants and essential oils. However, all these great compounds disappear during the process of drying, so opt for fresh basil whenever possible to enjoy the most benefits. Basil can help reduce inflammation in the body, lower blood pressure, fight free radicals, and reduce high blood sugar levels. Basil has antibacterial properties. 
  • No serious pest or disease issues. Keep an eye out for slugs, snails, and powdery mildews. Deer and rabbit resistant.
  • Pinch out flowerheads as they appear to ensure continued leaf growth. Cut back after flowering.
  • Propagate by seed in gentle heat in spring under glass or indoors.
  • Native to the Indian subcontinent and widespread as a cultivated plant throughout the Southeast Asian tropics.
