It has various common names such as white sage, hummingbird sage, desert sage, and mint bush sage. The plant possesses several medicinal properties that have been used in many traditional medicines for centuries. It belongs to the lamiaceae family and is also known as the 'Lunar honeysuckle.'

Physical Description

The plant grows to an average height of 30-60 cm tall, and it branches out a lot. The leaves are about 2-5cm long and wide, with lighter green undersides and velvety, white-hairy upper sides. They are oblong-oval to kidney-shaped, with toothed or wavy margins. They have a strong odor when crushed or bruised. The flowers are white to light pink in color, and they grow in pairs or in clusters of up to six flowers. It blooms from June to September.

Medicinal Uses

The plant has been used since ancient times for its medicinal benefits. Notonia lunulata contains several chemical compounds, such as diterpenoids and flavonoids, that give the plant anti-inflammatory, antimicrobial, and antioxidant properties. The plant extracts are used for treating various health issues such as respiratory infections, fever, headaches, anxiety, and depression.

Cultural Significance and Uses

The plant is highly valued in the traditional medicine of Ethiopia and Kenya. Some ethnic communities believe that it contains magical and protective properties, making the plant an important part of their spiritual and cultural life. Notonia lunulata is also a highly sought-after ingredient used with other herbs to make incense and perfumes. Some people use the plant as a natural insect repellent.

Cultivation

Notonia lunulata easily propagates through seedlings, and it prefers full sun to partial shade. It thrives in well-drained soils and can tolerate drought better than most plants. The plant is primarily cultivated for its medicinal and ornamental purposes and can be grown in a wide range of soil types. It is a hardy plant that requires minimal maintenance once established.

Light Requirements

Notonia lunulata requires bright, indirect light to grow properly. It should be placed in a spot that receives full to partial sunlight, as exposure to direct sun can damage the plant.

Temperature Requirements

The ideal temperature for the growth of Notonia lunulata ranges from 18 to 24°C (64 to 75°F). It can withstand occasional drops in temperature but cannot survive below 10°C (50°F) or above 30°C (86°F). Avoid placing the plant in areas with low temperatures, such as near drafts or air-conditioners, as they can affect its growth.

Soil Requirements

Notonia lunulata grows best in a well-draining soil mix that is rich in organic matter. The soil should be kept moist but not waterlogged, as excess water can cause root rot. It also prefers slightly acidic soil with a pH level of 6.0 to 7.5.

Cultivation Methods

Notonia lunulata is a shrub that is easy to cultivate. It does well in warm climates. The plant thrives in full sunlight but can also grow in shady locations. It prefers well-drained soil with a slightly acidic pH of 5.5 to 6.5. The shrub can be propagated through stem cuttings or by sowing seeds.

Watering Needs

Notonia lunulata requires a moderate amount of water. The soil should be kept moist but not soaking wet. Water the plant regularly, especially during hot and dry periods. A good rule of thumb is to water deeply once a week, rather than light watering multiple times a week. Overwatering can lead to root rot, which can be fatal for the plant.

Fertilization

Fertilizing Notonia lunulata can help promote growth and flowering. Use a balanced fertilizer with equal ratios of nitrogen, phosphorus, and potassium. Fertilize the plant once every month during the growing season, which is typically in spring and summer. Fertilizer should be applied according to the instructions on the packaging. Avoid over-fertilizing as this can lead to burnt leaves and root damage.

Pruning

Pruning can help maintain the shape and size of Notonia lunulata. Prune the shrub in the early spring before new growth begins. Remove any dead or damaged branches, as well as any crossing or rubbing branches. Pinch back the tips of the young branches to encourage branching and bushiness. Heavy pruning can be done every few years to rejuvenate the plant.

Propagation of Notonia lunulata

Notonia lunulata (Chiov.) Chiov. is a succulent plant that can propagate through different methods such as seeds, stem cuttings, and offsets. However, the most effective way to propagate this plant is through stem cuttings.

Propagation by stem cuttings

Propagation by stem cuttings is the easiest and most efficient method for Notonia lunulata. Here are the steps:

1. Take a stem cutting from the mother plant, making sure it is at least 2 inches long.
2. Let the stem cutting dry in a shaded area for a few days until the wound at the base of the stem is callused over.
3. Prepare a potting mix that is well-draining and suitable for cacti and succulents.
4. Plant the stem cutting in the potting mix, making sure the callused end is placed in the soil.
5. Water the cutting and place it in a shaded area until it develops roots.
6. Once roots have developed, the cutting can be moved to a brighter area with indirect sunlight.

Propagation by stem cuttings should be done during the growing season, which is usually in the spring or summer. It is important to use a well-draining soil mix to prevent overwatering and to provide sufficient protection from direct sunlight until the plant has acclimatized.

Disease Management

Notonia lunulata is a beautiful plant that is generally resistant to diseases. However, in certain conditions, it can be affected by diseases such as:

• Leaf Spot: This disease causes small, dark spots on leaves that later turn yellow and fall off. It can be caused by over-watering and high humidity. To manage this, avoid overhead watering and ensure good air circulation by trimming the plant.
• Root Rot: Over-watering can cause the roots of Notonia lunulata to rot. To manage this, avoid over-watering and ensure the soil is well-draining. Remove the affected plant from the soil and repot in fresh, clean soil.
• Powdery Mildew: This fungus appears as white powder on the foliage, causing wilting and yellowing of the leaves. To manage this, improve air circulation and reduce humidity. Applying a fungicide can also help.

Pest Management

Notonia lunulata is generally not a preferred host for pests but can be affected by some pests such as:

• Spider Mites: These pests are common in dry conditions and can be easily identified by their webs on the foliage. To manage this, keep the plant moist and increase humidity around the plant by misting the leaves. Applying insecticidal soap can also help.
• Mealybugs: These pests are commonly found in warm and humid conditions. They appear as a white, cotton-like substance on the foliage. To manage this, use a cotton swab dipped in alcohol to remove the bugs from the foliage. Applying insecticidal soap can also help.
• Thrips: These pests are tiny, sucking insects that attack leaves and flowers. They cause discoloration and distortion of the foliage. To manage this, apply insecticidal soap or neem oil to the foliage.
