Day blooming jasmine is a highly fragrant plant that is actually not a true jasmine. Instead, it is a variety of jessamine with the genus and species name Cestrum diurnum. Jessamines are in the Solanaceae family of plants along with potatoes, tomatoes and peppers. Read to learn more about growing day jasmines, as well as helpful tips on day blooming jasmine care.
Day Jasmine Varieties
Day blooming jasmine is a broadleaf evergreen shrub that grows 6-8 feet (1.8-2.5 m.) tall and 4-6 feet (1.2-1.8 m.) wide. It is native to the West Indies and is widely cultivated in India. Day blooming jasmine is hardy in zones 8-11. In late spring to midsummer, day blooming jasmine bears clusters of tubular white flowers that are highly fragrant. At sunset, these flowers close up, capturing their fragrance within them.
After the flowers fade, day blooming jasmines produce dark purple-black berries that were once used to make ink. The fragrant flowers attract many pollinators to the garden, while the berries provide food for a variety of birds. Because day blooming jasmine berries are eaten and digested by birds and some small mammals, its seeds have escaped cultivation. These seeds quickly germinate and take root almost anywhere where they come into contact with suitable soil and sunlight.
Day blooming jasmine was introduced to areas of the Southeastern U.S., the Caribbean and Hawaii as a tropical garden plant. However, now in many of these locations, it is considered an invasive species. Be sure to check with your local extension office for day blooming jasmine’s invasive species status before planting it in your garden.
Some popular Cestrum varieties that are also fragrant and similar in growth and habit include night blooming jasmine, yellow cestrum, and the red and pink varieties of cestrum known in some locations as butterfly flower.
How to Grow Day Blooming Jasmine Plants
Also known as Chinese inkberry, white chocolate plant and Din ka Raja (king of the day), day blooming jasmine is mainly grown for its highly fragrant blooms, which are described as having a chocolate-like scent. In the landscape, it is grown as a privacy hedge or screen because of its evergreen nature and tall, columnar habit.
Day blooming jasmines prefer to grow in full-partial sun and in moist soils. They are not particular about soil pH or quality. They are oftentimes found growing wild in vacant lots, pastures and along roadsides, where their seeds have been deposited by birds. Their growth rate is so fast that they may not even be noticed until they have grown out of control.
Plants can be kept under control in garden or patio containers with regular pruning following the bloom period as part of regular day blooming jasmine care. Because of their sweet, intoxicating fragrance, they make excellent patio plants or specimen plants grown near windows or outdoor living spaces where the fragrance can be enjoyed.

How to Grow Jasmine Indoors
Fragrant, delicate, and exotic – there is so much to love about the vining, twining jasmine plant. If you’re looking for a delightful plant to grow indoors, look no further. Jasmine is the decorative indoor plant you have been looking for.
Many gardeners shy away from growing jasmine indoors, as they believe it will be too challenging a task. On the contrary, jasmine is not difficult to grow inside if the proper growing conditions are provided. With a bit of care and practice, jasmine can be cultivated indoors by even the most novice of gardeners.
If you’re considering growing jasmine indoors, consider these tips to help your plants survive and thrive in your home.
Growing Jasmine Indoors
"Jasmines do best in a bright, sunny location potted in a slightly acidic, well-drained soil with good organic content," Hachadourian says. While jasmine should get at least six hours of sunlight each day, Barnett adds that it should be strong, indirect light. Also keep in mind that you can cut back on the feeding and fertilizing process during the winter since the growth slows down during that time. And don't forget to make sure it's in the proper planter. "Hanging planters are popular, as they allow for vines to cascade from containers, creating a unique and striking visual effect," Barnett says.
Since jasmine grows rapidly, pruning will be a necessary step to keep the plant in shape, encourage branching, and help them bloom. The best time to prune them is just after flowering, the garden experts say. Shortly after your indoor jasmine plants start flowering, you will need to prune back by half an inch (there should be at least three to six sets of leaves on each branch). You can train vining jasmine species on a trellis or allow them to cascade out of a basket. "Shrubby species like Jasminum sambac should be only pruned in late spring and mid-summer to encourage more branches and flower buds over time," Hachadourian adds. "You will definitely need some space to allow them to mature, but the intoxicating fragrance is absolutely worth it." As the fall season nears, you can then stop pruning and let the plants experience cooler temperatures so the buds can set—especially Jasminum polyanthum. Evening temperatures from about 50 to 55 degrees are best to encourage flower buds.
The word Trachelospermum comes from the Greek words meaning seed and neck. The word asiaticum means ‘from Asia’ and the plant does indeed have its roots in Asia.
It is native to India, China, Korea, Japan, Indo-China, and Malaysia. It is most commonly found growing in mountain forests and scrub, where it climbs up trees.
It was first described in 1846 by the Bavarian physician and naturalist Philipp Franz von Siebold.
Siebold traveled and studied in Japan from 1823 to 1829. When he arrived back in Germany, he was assisted by Joseph Gerhard Zuccarini to describe the plant. The plant was originally called Malouetia asiatica.
