Basil : Ocimum tenuiflorum, Holy Basil (also tulsi, tulasī)
aromatic plant in the family Lamiaceae
Ocimum tenuiflorum, Holy Basil (also tulsi, tulasī), is an aromatic plant in the family Lamiaceae which is native throughout the Eastern World tropics and widespread as a cultivated plant and an escaped weed. It is an erect, much branched subshrub, 30–60 cm tall with hairy stems and simple, opposite, green leaves that are strongly scented. Leaves have petioles, and are ovate, up to 5 cm long, usually slightly toothed. The flowers are purplish in elongate racemes in close whorls. The two main morphotypes cultivated in India and Nepal are green-leaved (Sri or Lakshmi tulsi) and purple-leaved (Krishna tulsi).
Tulsi is cultivated for religious and medicinal purposes, and for its essential oil. It is widely known across South Asia as a medicinal plant and an herbal tea, commonly used in Ayurveda, and has an important role within the Vaishnavite tradition of Hinduism, in which devotees perform worship involving tulsi plants or leaves.
The variety of Ocimum tenuiflorum used in Thai cuisine is referred to as Thai holy basil, or kaphrao (กะเพรา); it is not be confused with Thai basil, which is a variety of Ocimum basilicum.

- Growing Conditions
- Warm, Hot
Basil is very unhappy if it isn't warm, so in cooler areas it should be in the warmest spot in the garden. If this still isn't warm enough then grow it under cloches. It will tolerate some shade when growing in hot climates, but does better in full sun.
- Outdoor Growing Temp
- 60°F - 90°F
- Min Outdoor Soil Temp

Basil needs warm (75ºF - 85ºF) soil.

- Water
- Moderate
Basil likes evenly moist soil.
- Feeder
- Light
Low nitrogen. Low potassium. Low phosphorous. Basil isn't a very hungry plant, but for maximum leaf production it should be given fertile soil.
- Suitability
- High heat, Partial shade
- Small Gardens?
- Yes
- Containers?
- Yes
Basil does well in containers as small as a one gallon plant pot, and is great to grow on the kitchen windowsill (especially in cool climates). Transplant one seedling per 6" pot or 3 seedlings per 12" pot. Because basil is a heat-loving plant, it is crucial to place the container in an area with access to at least 4 hours of sunlight per day. Basil requires temperatures of 75 degrees F or higher in order to thrive, so it's not the best option for Winter growing (unless you keep your house well-heated.) Use well-drained, nutrient-rich potting soil and keep the soil moist but not overly wet.
