Description:
Depending on the maturity of the plant, African Blue basil leaves can vary greatly in size. They have an oval, slightly tapering form that ends in a delicate tip on the non-stem end. The leaves have smooth, broad, flat surfaces with noticeable veining and somewhat serrated edges. African Blue basil leaves are dark purple when young, turning purple-green and then bright green as they get older. The leaves also have noticeable maroon veining on the surface and dark purple and green speckling on the underside.
The plants have fuzzy, purple-green stems beyond the leaves, as well as long stems with a cluster of tiny purple buds that open into lavender flowers.

Plant Care
- Sunlight
Like all basils, African Blue Basil enjoys exposure to sunlight. Make sure it receives at least 5 to 6 hours of sunlight for the greatest flowers. The more, the better.
- Soil
Rich, well-draining soil that has a pH range of slightly acidic to slightly alkaline is ideal for the growth of African blue basil. To cultivate this herb, you can use any standard soilless potting mix.
When planting, add lots of organic matter or compost to the growing medium to ensure its success. It performs well at a pH of 6.0 to 7.5.
- Water
When watering this plant, the ideal practice is to wait until the topsoil is somewhat dry to the touch. AVOID watering the plant every day. In cold and rainy weather, minimize watering and avoid spraying water on foliage.
- Fertilizer
Fertilize African Blue Basil with half-strength balanced liquid fertilizer every two to three weeks.
Slow growth and fading leaves may be signs of a magnesium shortage. One tablespoon of Epsom salt dissolved in one gallon of water is the remedy; use it once every two to three weeks.
- Pruning and Clipping
Consistent trimming will produce healthier, bushier leaves. Remove the blossoms as soon as possible to allow the basil plant to focus its energy on growing additional foliage. Pinch off the uppermost pair of leaves to promote lateral growth as well.
