African Blue Basil Ocimum 'African Blue'
ABOUT
The African Blue basil is a perennial herb with a striking appearance, known for its vibrant and lush foliage intermingled with floral hues. The leaves of this plant are green but come with a purplish tinge on the undersides and sometimes on the edges, giving it an ornamental contrast that is both eye-catching and unique. It's the interplay of purple and green that really sets this basil apart, often reflecting a gradient of colors that enhance its decorative appeal. Tiny veins may appear more pronounced on the purple sections, adding to the textured look of the leaves. The plant also features flowers; these blossoms are a shade of lavender-pink, adding a spritz of color that stands out against the green and purple leaves. The flowers are arranged in spikes, which emerge from the central stem, lending a vertical aspect to the plant's shape. This contrast of colors not only caters to the aesthetic sense but also attracts pollinators like bees and butterflies, which find the flowers irresistible. African Blue basil leaves are slightly serrated on the edges, with a soft and somewhat delicate touch. However, despite the delicate look, the plant itself is robust and hearty, with stems that are slightly woody at the base, reflecting the plant's perennial nature. These stems contribute to the sturdy structure of the plant and are characterized by their square shape, which is typical of basils. The fragrance of this basil is an aromatic blend of traditional basil scent with a hint of mint and other herbaceous notes making it a delight in the garden.

WaterThe African Blue Basil needs consistent moisture but does not like to sit in waterlogged soil. Therefore, it's important to water this plant when the top inch of the soil feels dry to the touch. An ideal watering schedule would be approximately once a week with about one to two gallons of water, depending on the size of the plant and environmental conditions. During hot or windy weather, the plant might require more frequent watering. It is best to water this basil early in the morning, at the base of the plant, to ensure the foliage does not remain wet overnight, which can promote disease.
LightAfrican Blue Basil thrives in full sun, which means it should receive at least six to eight hours of direct sunlight each day. The best spot for this plant is an area with ample morning sunlight and some afternoon shade in hot climates to prevent scorching. Placing African Blue Basil in a south-facing garden or window where it will receive plenty of light is ideal for vigorous growth.
TemperatureAfrican Blue Basil prefers warm temperatures and will thrive best when maintained between 50°F and 80°F. It's important to protect the plant from temperatures that drop below 50°F, as it is not frost hardy. Ideally, keep the African Blue Basil in an area where the nighttime temperatures do not fall below the 50°F mark to ensure it continues to grow and produce.
PruningPruning African Blue Basil promotes bushier growth and prevents it from getting leggy. It is advisable to pinch off the growing tips and flower buds to encourage the plant to branch out and to focus its energy on growing leaves rather than flowers. Prune or harvest the leaves regularly, especially in the early morning when the essential oils are strongest. The best time for heavy pruning is in the spring or early summer when the plant is in its active growing phase.
CleaningAs needed
SoilAfrican Blue basil thrives in well-draining, fertile soil with a pH between 6.0 and 7.5. A mix of two parts potting soil, one part perlite or coarse sand, and a generous amount of compost is ideal. Regularly adding organic matter can enhance soil fertility and structure.
RepottingAfrican Blue basil should be repotted every 1-2 years or when the plant seems root-bound. Spring is the best time for repotting, just before the growing season begins, to provide fresh nutrients and room for growth.
Humidity & MistingAfrican Blue basil prefers moderate to high humidity levels, ideally between 40-60%. If the air is too dry, the leaves may wilt or develop brown edges, so maintaining proper humidity is important for its health.
Suitable locationsIndoor
Place in bright, indirect light and keep soil moist.
Outdoor
Plant in full sun, use well-draining soil, water regularly.
Hardiness zone

Life cycleThe life cycle of the African Blue Basil (Ocimum 'African Blue') begins with seed germination, which is triggered by warm temperatures and moist conditions. Once the seeds sprout, the young seedlings establish themselves with a set of true leaves, after which they transition into a phase of vigorous vegetative growth, developing stems and more complex leaf structures. During the vegetative stage, African Blue Basil can be propagated through cuttings, which root easily and create genetic clones of the parent plant. As it matures, the plant enters the flowering stage, producing tall spikes of small, attractive purple flowers that are highly attractive to pollinators. After pollination, the flowers set seeds that will mature, dry, and eventually disperse to begin a new cycle. While African Blue Basil is a perennial plant in warm climates, it is often treated as an annual in temperate regions, as it does not tolerate frost.
PropogationPropogation time
Spring-Early Summer
The most popular method of propagating the African Blue Basil is by taking stem cuttings. This is ideally done in the warmer months of spring or early summer when the plant is actively growing. To propagate, you would cut a 4 to 6-inch (10-15 cm) long stem from a healthy parent plant, making sure the cutting includes at least a couple of leaf nodes. Strip off the leaves from the bottom half of the cutting, and then place the stem in a glass of water or moist soil. Roots should begin to develop within a week or two. Once the roots are a few inches long, the cutting can be transplanted into a pot or the ground. This method is effective because it maintains the genetic consistency of the plant, ensuring that the new plants are true to the parent's characteristics.
