Fast-growing woody plant called cestarum nocturnum yields night-blooming jasmine. The plant isn’t a real jasmine, but it is a member of the Solanaceae family, which also contains potatoes and tomatoes. Its tubular, greenish-white or yellow blooms, which release a strong fragrance at night and entice butterflies and other pollinators, are where it gets its name. The shrub blooms continuously throughout the summer and has a lengthy bloom period.
The shrub spreads out spontaneously and develops quickly from seed in the spring. Despite these aggressive invasive characteristics, it is frequently cultivated in patio pots or as a thick border hedge (some experts refer to it as a “garden thug”). Additionally, it thrives in greenhouses or indoor environments.
Jasmine with night blooms reaches heights of 8–10 feet (2.5–3 m) and widths of 3 feet (91.5 cm). Night-blooming jasmine is a great choice for privacy hedges and screens because to its evergreen nature and tall yet columnar growth pattern. From early spring until late summer, it produces clusters of tiny, white-green blooms. White berries that emerge after the blooms start to fade draw a variety of birds to the garden.
The night-blooming jasmine doesn’t have a very striking look overall. The tiny, tubular blossoms of night-blooming jasmine, on the other hand, open when the sun sets, filling the yard with a wonderful scent. Night-blooming jessamine is frequently planted next to a house or patio so that people may enjoy its perfume because of its aroma.
The night-blooming jasmine is toxic to people and animals in all parts, but notably the berries.
It’s advisable to leave night-blooming jasmine at least four feet apart from other plants due to their extensive roots. When the final frost has passed in the spring, plant them.
Note: Night-blooming jasmine grows best in damp environments and can become out of hand very rapidly in tropical areas. It is regarded as one of the most invasive plant species in Hawai’i, as well as Florida, Kaua’i, Oahu, Maui, and Lanai.
Although it may survive in little shade, this shrub thrives in at least six hours of direct sunshine each day. The amount of blossoms might be reduced by too much shadow.
Soil
Any healthy, well-draining soil is ideal for growing night-blooming jasmine.
These plants love moisture. For them to produce wholesome, fragrant blossoms, they require constant watering. They may require saturating several times per week while establishing, and then at least once per week once they have established roots throughout the growth season. Established plants won’t need much irrigation during the winter dormancy.
The optimal conditions for night-blooming jasmines are warm temperatures and high humidity. Although mature plants can withstand temperatures as low as 25 degrees Fahrenheit, young growth frequently dies in conditions below 35 degrees. You should cultivate your plant in a container that you can bring indoors if the wintertime lows fall below this.
These plants thrive in rich soil and will benefit from monthly fertilizer applications while they are becoming established. Mature plants might benefit from an annual early spring feeding to encourage strong blooms.
Annual pruning in the fall, following flowering, promotes dense, compact new growth and lessens the plant’s invasive characteristics since the berries’ seeds won’t be spread by birds that eat them.
This fast-growing shrub is simple to cultivate from cuttings, as one might anticipate.
Healthy cuttings from the plant can be stored in water until new roots appear if they are taken in the fall. They can then be moved to a sunny location with wet, healthy soil. Wait until the spring, when the winter weather has passed, to transfer them outside.
Night-blooming jasmine is difficult to grow from seed because in untamed soils, they might lay dormant for many years. It is best to let the plant’s berries mature and fall to the ground naturally. The seeds from these berries can be sown on the surface of warm, wet compost. If germination is successful, shoots should start to develop in about a month.
There aren’t many issues with these hardy, deer-resistant plants. But occasionally, aphids and caterpillars may strike. A stream of water can occasionally be used to blast these pests away, and insecticidal soaps or neem oil can also be used to manage aphids. The easiest way to remove caterpillars from your plants is by hand, but certain species might develop into stunning pollination butterflies, so you might not want to do that.
The majority of plants’ flowers open as a consequence of a localized extension of the petals without any further plant development. For this elongation to take place, plants need a source of energy for cell wall loosening and expansion. Most often, external exogenous elements, such as the length of light and darkness, temperature, relative humidity, and light quality and quantity, affect when flowers open. On the other hand, it is thought that internal endogenous rhythms that regulate the plant’s bloom cycles have an impact on night blooming jasmine.
As contrast to exogenous rhythms, which are impacted by outside changes like a drop in temperature or a rise in light intensity, endogenous rhythms are the regulatory control that the plant’s internal genes have over itself. So, even in an environment with constant light and temperature, night blooming jasmine will continue to bloom in a regular cyclical pattern. In nature, the bloom and odor cycle is timed to begin every 24 hours from July through October during the summer. In low temperatures, such as those encountered on summer evenings, night blooming jasmine will bloom for a longer period of time in an artificially controlled environment. On the other hand, when temperatures are increased to a level more equivalent to summer daytime temperatures, the bloom cycle is shortened.
Night-blooming jasmine requires little care once it has established itself and is placed in a damp, sunny area. However, if left unchecked, it can grow out of control.
The species is a well-liked houseplant. You only need to place it where it can receive enough light to promote profusion of flowers, such as near a bright window or in a conservatory. It’s a plant that thrives in humidity and can thrive in a bright bathroom. But be careful that the floral scent might be rather strong up close.
The shrub and other Cestrum species with yellow blooms are frequently mistaken. For instance, orange jessamine and willow-leaved jessamine (Cestrum parqui), both spreading shrubs with tubular scented blooms, are related species (Cestrum aurantiacum).
Night-blooming jasmine is toxic to both humans and animals. When taken, the plant might cause digestive issues and is poisonous in all ways. The mouthwatering scent of night-blooming jasmine flowers can also cause headaches, nausea, and respiratory problems in some people.
Once it has grown and is planted in a moist, sunny spot, night-blooming jasmine needs minimal maintenance. But if it’s allowed to continue, it may become out of hand.
Once the water has drained from the Night Blooming Jasmine’s container, wait until the earth seems dry before watering it once again. These plants do not do well with excessive moisture in the soil, thus they demand well-drained or averagely-drained soil. Too much water will cause the mold to proliferate and cause the roots of this plant to rot.
However, if it’s really dry or scorching outside, up the frequency. Make careful to wait between applications to allow the soil dry up again.
