Description
Cestrum nocturnum, commonly known as Night-Blooming Jasmine, is a fragrant, easy-to-care-for evergreen shrub that delights with its small, tubular white or yellow-green flowers that bloom at night. These flowers release a sweet, intoxicating fragrance that is especially noticeable in the evening, filling the air with its soothing aroma. This shrub’s dark green, lance-shaped leaves provide a lush backdrop for its striking flowers, and in some regions, it can also produce small, dark berries in late summer. While its blooms are most fragrant at night, it is an attractive addition to gardens, patios, or balconies due to its pleasant scent and attractive foliage.
Growth Habit:
Night-Blooming Jasmine is a fast-growing, semi-woody shrub that can grow 4 to 10 feet tall, with a spread of about 3 to 5 feet. It has a bushy growth habit with slender, arching branches. As it matures, it can develop a more upright form but may require pruning to maintain shape and size, especially if grown as a hedge or container plant. The plant is typically grown outdoors in warmer climates but can also be grown indoors in containers, especially during the cooler months.
Watering Instructions:
Cestrum nocturnum prefers regular watering, but like many shrubs, it does not tolerate standing water. Water the plant deeply when the top 1-2 inches of soil have dried out, ensuring that the root zone is adequately hydrated. During the growing season (spring and summer), it may need more frequent watering, but in the cooler months (fall and winter), you should reduce watering to avoid overwatering. Make sure the soil is well-draining, as this plant is susceptible to root rot in waterlogged conditions.
Soil Needs:
This shrub thrives in well-draining, fertile soil that is rich in organic matter. It prefers slightly acidic to neutral pH, ranging from 6.0 to 7.0. For optimal growth, you can amend the soil with compost to enhance its drainage and provide essential nutrients. A loamy or sandy soil mix will ensure that the roots stay healthy and avoid stagnation. The plant is adaptable to a variety of soil types but must not sit in overly compacted or soggy soil.
Indoor or Outdoor Tips:
Indoor Care: When grown indoors, Night-Blooming Jasmine requires a bright location with indirect sunlight, ideally near a sunny window. The plant will thrive in temperatures between 65°F and 75°F and can tolerate slightly cooler conditions during the winter months. Ensure good air circulation to avoid fungal issues and water the plant thoroughly but allow the soil to dry slightly between waterings. A humid environment will promote healthy growth, so placing the plant on a humidity tray or using a room humidifier can help if you live in a dry climate.
Outdoor Care: In USDA hardiness zones 9-11, Cestrum nocturnum can be grown outdoors. It prefers full sun to partial shade but will flower and produce the most fragrance in a sunny location. Ensure the plant is protected from cold winds and frost, as it is sensitive to freezing temperatures. In regions with frost, it is best to grow the plant in a container so that it can be brought indoors during the colder months. Regular pruning will help maintain its shape and encourage more abundant blooming. As it is a fast grower, occasional trimming may be required to prevent it from becoming too unruly.
