Cestrum nocturnum, commonly known as Night-blooming Jasmine or Queen of the Night, is a tropical shrub in the Solanaceae family. Renowned for its powerful fragrance, it releases its perfume at night, making it a popular choice for gardens and landscapes designed to be enjoyed after sunset. Native to the Americas, this plant is valued for its ornamental and aromatic qualities. Key Features: Height and Growth Habit: A fast-growing, evergreen shrub that typically reaches 1–4 meters (3–13 feet) in height. It has a bushy and somewhat sprawling growth habit, making it suitable for hedges or as a standalone feature. Leaves: The leaves are lance-shaped, smooth, and bright green, providing a lush backdrop to the flowers. Flowers: Small, tubular, pale greenish-yellow flowers cluster at the ends of branches. The blooms are not particularly showy during the day but emit a strong, sweet fragrance at night. Flowering occurs throughout the year in warm climates, with peak blooms in spring and summer. Fruit: Produces small, white berries containing seeds. While the berries are attractive, they are toxic if ingested. Growing Conditions: Climate: Thrives in tropical and subtropical climates, preferring USDA zones 9–12. It can tolerate light frost but may lose leaves in cooler weather. Soil: Prefers well-drained, moderately fertile soils. It is adaptable to various soil types, including sandy and loamy soils, as long as there is good drainage. Light: Grows best in full sun to partial shade. Too much shade may reduce flowering. Watering: Requires moderate watering. Keep the soil moist but not waterlogged, especially during the growing season. Care and Maintenance: Pruning: Regular pruning helps maintain shape, control size, and encourage bushier growth. Prune after the main flowering period to stimulate new blooms. Fertilization: Apply a balanced fertilizer in spring and summer to enhance flowering and foliage growth. Mulching: Use mulch to retain soil moisture, suppress weeds, and protect roots in cooler climates. Pest and Disease Management: Generally pest-resistant but may occasionally attract aphids, whiteflies, or spider mites. Overwatering or poor drainage can lead to root rot. Uses: Ornamental: Commonly used as a hedge, screen, or specimen shrub in gardens. Its fragrance makes it ideal for planting near patios, windows, or pathways. Night Gardens: Perfect for moonlight or night gardens, where its evening fragrance can be enjoyed. Pollinator Attraction: The flowers attract nocturnal pollinators like moths, enhancing garden biodiversity. Propagation: Cuttings: Propagate easily from semi-hardwood cuttings taken during the growing season. Use rooting hormone for better success. Seeds: While seeds can be used, they may take longer to germinate and grow into mature plants. Cautions: Toxicity: All parts of the plant, particularly the berries, are toxic if ingested by humans or animals. Care should be taken when planting around children or pets. Invasiveness: In some regions, Cestrum nocturnum is considered invasive due to its rapid growth and ability to self-seed. Check local regulations before planting. Strong Fragrance: While the scent is appealing to many, it can be overpowering in enclosed spaces or for those with sensitivities. Conclusion: Cestrum nocturnum is a delightful addition to tropical and subtropical gardens, offering lush greenery and a captivating night-time fragrance. With proper care and placement, it can transform any outdoor space into a serene and aromatic retreat. Its rapid growth and low maintenance needs make it an excellent choice for hedges or as a feature plant, especially in gardens designed to be enjoyed after sunset.
