Spatial Distribution

Some of its common names give a hint on where this plant originated, which is in Asian countries such as Korea, Japan, India, and China. Given its origins, this plant thrives in USDA Zones 7 to 11.

Growth Habits

The Asian jasmine is an annual broadleaf that is widely cultivated to serve as a groundcover or vine in a landscape due to its vast growth and development.

Given its fast growth rate, it can extend up to 2 feet in height and 10 to 12 feet in width given that there are little to no supporting infrastructures present. In 10 years or so, this vine may grow up to more than 25 feet in height and width.

Aside from bearing leaves all year round, small and simply beautiful flowers are seen during May to June right before summer just in time for people to enjoy the outdoors.

Leaves

On regular days, the Asiatic jasmine bears green and waxy foliage. However, the leaves change their color to dull-brown and brick red at the onset of Fall.

Flowers

The common name Asian Star jasmine describes what this plant’s flowers look like. Its color ranges from creamy white, yellow, tan, or gold. The small florets are known to have a star-like pinwheel shape with 4 to 5 petals.

Each floret forms a bundle of florets wherein one terminal flower will emerge followed by lateral blooms. Thanks to these characteristics, the flowers serve as an invitation for pollinators such as birds and insects.

Fruit and Seeds

Eventually, after flowering, the vine reaches maturity and creates pods that bear seeds for reproduction. 


Asian Jasmine Grow and Care Tips

For someone to successfully take care of a plant, it is important to know what the plant needs. A keen observation in combination with acquired knowledge about that plant will help solve potential problems that may arise in the landscape.

Below are the basic requirements to know how one can look after the Asian jasmine vine.

Sun Requirement

The optimal growth of the Asiatic jasmine will be obtained if exposed to full sunlight. It should be uninterrupted and lasts for at least 6 hours daily. Although it also tolerates partial shade, the formation of pigment and production of flower buds may be problematic.

Water Requirement

Moderate amounts of water supplied frequently are enough for this vine to grow. However, in places wherein rain is prominent, watering may be done less frequently. On the other hand, watering should be done more frequently during hot summer days.

If rainfall is happening often, less watering is needed. Regular watering should be done during the hotter months.

Temperature and Humidity

A warm and moist environment is this vine’s favorite environmental condition.

Soil Requirement

The Asian jasmine is a versatile vine as it can thrive in almost any soil as long as there is good drainage. Either sand, clay, or loam soils are suitable for the vine. Moreover, a medium with a large water holding capacity favors the growth of this vine, especially in hot months.

Aside from the type of medium, the space needed is also to be considered since this vine is a fast grower. At least 3 feet by 6 feet planting space is enough for the vine to grow and bloom without disrupting other plants in the vicinity.

Fertilizer Requirement

Generally, the application of external fertilizer is not needed as long as the soil is rich in organic matter.

This might lead to soil toxicity. However, if the goal is to hasten the development of the Asiatic jasmine, the application of slow-release fertilizers for at most once a month may be done. Only do this when the vine is at its young stages.

Once established, the application of slow-release fertilizers should be limited to once a year.

Maintenance Activities

The maintenance activities to be done for the Asiatic jasmine are for keeping it in shape and training. That is why trimming the vine when it exceeds the desired shape or height is often done with the discretion of the grower.

Removal of dead plant parts is also advised as it helps lessen the plant’s susceptibility to diseases. Moreover, this vine belongs under the Group 11 pruning wherein pruning is scheduled concerning its blooming months. Lastly, as the plant ages, rejuvenating pruning may be done. 

Propagation

The Asiatic jasmine vine is propagated by planting semi-hardwood cuttings or by layering. In both ways of propagation, choosing stems that are mature and actively growing is necessary.

Also, the planting medium should have proper drainage and moisture. For the cuttings, dipping the cut end into rooting hormones aids in the formation of roots. When the plants are ready to be transplanted, provide at least 1.5 feet apart per plant.
