Night jasmine, scientifically known as Cestrum nocturnum, is a beautiful and highly fragrant plant that blooms primarily during the evening and nighttime hours. Known for its intoxicating scent, which becomes more potent after dusk, this aromatic shrub is a favorite among gardeners who want to enjoy its beauty and fragrance under the stars. In this comprehensive guide, we will explore how to grow and care for this evening-blooming plant, its flowering season, container cultivation techniques, and even explore its use in perfumery. We’ll also provide tips for those in the USA looking to cultivate this alluring specimen.
What Is Night Jasmine?
This tropical shrub is native to the West Indies and parts of South Asia. Despite its name, it is not a true jasmine plant but belongs to the Solanaceae family, which also includes tomatoes and potatoes. The plant is well-known for its small, tubular flowers that bloom at night, releasing a sweet, heady scent that attracts pollinators such as moths.
This evergreen shrub can grow to a height of 10-12 feet under the right conditions, making it a standout feature in gardens or as part of a larger landscaping project. The flowers are usually white or light green, and while the blooms themselves are quite small, their fragrance is what truly sets them apart.
Blooming Season and Flowering Patterns
The flowering period is one of this plant’s most notable features. The shrub typically blooms during the warmer months, from spring through fall, with peak flowering occurring during mid-to-late summer. The flowers open up in the evening and continue to release their fragrance throughout the night, making them a popular choice for moonlight gardens or areas where people enjoy spending time outdoors in the evening.
In tropical and subtropical climates, Cestrum nocturnum may bloom year-round, though in cooler climates or areas with frost, the plant will go dormant in winter and resume blooming in the spring.
Essential Growing and Care Requirements
Growing and caring for this fragrant shrub requires attention to its specific needs, but with the right care, it can thrive and provide years of enjoyment.
Planting Guidelines
Location: This aromatic plant prefers full sun to partial shade. It thrives best in areas that receive at least 6 hours of sunlight per day, though it can tolerate some afternoon shade in hotter climates.
Soil: The shrub prefers well-draining soil that is rich in organic matter. If you are planting in garden beds, amend the soil with compost to ensure proper nutrients.
Watering: Keep the soil evenly moist, especially during the growing season. Water deeply once or twice a week, depending on the weather. This tropical specimen does not like to sit in waterlogged soil, so good drainage is essential.
Temperature and Humidity: As a tropical plant, Cestrum nocturnum thrives in warm temperatures and prefers a humid environment. It is best suited for USDA hardiness zones 9-11. In cooler regions, consider growing the plant in containers so it can be moved indoors during the colder months.
Fertilization Schedule
Fertilize your evening-blooming shrub during the growing season (spring and summer) using a balanced, slow-release fertilizer or one specifically designed for flowering plants. This will promote healthy growth and abundant flowering. Reduce or stop fertilizing during the fall and winter months when the plant is not actively growing.
Pruning and Maintenance
Pruning is an essential part of caring for this fragrant specimen. To maintain a healthy shape and encourage more blooms, prune the plant after the flowering period has ended. Cut back any dead or damaged branches and trim to your desired size. Regular pruning will help keep the shrub looking neat and bushy, and it also helps improve air circulation around the branches, reducing the risk of diseases.
Container Gardening Success
For gardeners in cooler regions or those with limited space, growing this aromatic shrub in containers is an excellent option. This allows you to move the plant indoors when temperatures drop and control its growth more easily.
Tips for Pot Cultivation
Container Size: Choose a large pot, at least 12-16 inches in diameter, to give the plant plenty of room to grow. Ensure the container has drainage holes to prevent water from pooling at the roots.
Growing Medium: Use a high-quality, well-draining potting mix. You can add perlite or sand to improve drainage if necessary.
Watering Schedule: Potted plants tend to dry out faster than those in the ground, so check the soil regularly and water when the top inch feels dry. Avoid letting the soil become waterlogged, as this can lead to root rot.
Feeding: Since nutrients in containers can deplete faster, fertilize more regularly than you would for in-ground plants. Use a balanced liquid fertilizer every 4-6 weeks during the growing season.
Winter Protection: If you live in a cooler climate, bring your potted specimen indoors during the winter. Place it in a bright, sunny spot, such as a south-facing window, and reduce watering while the plant is dormant.
Capturing the Signature Scent in Perfumery
The alluring fragrance of this evening-blooming plant has inspired the creation of many perfumes. Known for its sweet, musky, and somewhat spicy aroma, fragrances featuring this flower capture the essence of its intoxicating scent, making them popular choices for evening wear or romantic occasions.
The scent is most potent during nighttime hours, which is why many perfumes that use this fragrance are designed to evoke mystery, allure, and elegance. Some perfumes blend this floral note with other evening bloomers, such as gardenia or tuberose, to create more complex and layered fragrances.
Benefits and Garden Value
Beyond its beauty and fragrance, this aromatic shrub offers several benefits that make it a desirable addition to gardens:
Incredible Fragrance: The primary benefit is its incredible scent. It can fill an entire garden with fragrance, especially during evening hours, creating a relaxing and inviting atmosphere.
Wildlife Support: The plant attracts nocturnal pollinators such as moths, making it a great choice for supporting local ecosystems and pollinator conservation.

Troubleshooting Common Issues
Like any plant, this fragrant shrub can face some challenges, but with proper care, most issues can be managed easily.
Pest Management
Common pests that may affect your evening-blooming plant include aphids, whiteflies, and spider mites. To keep pests under control, inspect your plant regularly and wash off any pests with a strong spray of water. In more severe cases, use insecticidal soap or neem oil.
Yellowing Foliage
If the leaves are turning yellow, this could be a sign of overwatering or poor drainage. Check the soil to ensure it is not too wet, and make sure the plant is getting enough sunlight.
Lack of Flowering
If your aromatic shrub isn’t blooming, it may not be getting enough light or nutrients. Ensure the plant receives at least 6 hours of sunlight per day and is fertilized regularly during the growing season.
Where to Purchase Plants
This fragrant specimen can be purchased at local nurseries, garden centers, or through online plant retailers. Many specialty nurseries that focus on tropical or fragrant plants will carry Cestrum nocturnum. Be sure to check availability, as this tropical plant may not always be in stock in cooler regions.
