Jasminum mesnyi aka Japanese Jasmine

Taxonomy

Jasminum mesnyi, also known as primrose jasmine or Japanese jasmine, is a scrambling evergreen shrub native to Vietnam and southern China. It can reach a height of 3 meters and a width of 1-2 meters, with fragrant yellow flowers that bloom in spring and summer. The cultivated form typically has semi-double flowers. Although not frost-hardy, it can be grown as a slender climber with suitable support, requiring regular pruning in confined spaces. It has been naturalized in Mexico, Honduras, and parts of the southern United States. This species has received the Royal Horticultural Society's Award of Garden Merit. Another related plant is the Japanese Star Jasmine (Trachelospermum asiaticum), which is an evergreen twining climber or ground cover. It produces clusters of highly fragrant star-shaped cream flowers during the summer. It is commonly used to grow along fences, walls, pergolas, and can be trained to climb over supports like arches or trellises.

How to care for Japanese Jasmine

Difficulty

With its straightforward care requirements, Japanese Jasmine is a hassle-free plant that anyone can enjoy.

Water

Japanese Jasmine should be watered regularly, allowing the soil to dry out between waterings.

Soil

Japanese Jasmine loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

To ensure optimal growth, the Japanese Jasmine prefers bright indirect light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

Dormancy

During the wintertime, it is common for Japanese Jasmine plants to go dormant and their growth rate may slow down. Therefore, the amount of waterings should be spaced out more.

Toxicity

The toxicity level of this plant has not been officially confirmed by Ploi. If there is a possibility of ingestion of plant material with an uncertain toxicity by you, a family member, or a pet, it is advisable to seek the assistance of a medical professional.

Humidity

No additional humidity is required for the Japanese Jasmine. Plants take in most of their water through their roots, not their leaves, therefore, watering the soil is the most effective way to supply humidity to your plants.

Fertilizer

Repotting the Japanese Jasmine is necessary either when it has doubled in size or once every year, whichever happens first. With fresh potting soil replenished annually, the plant will receive all the necessary nutrients, rendering the use of fertilizer unnecessary. Keep in mind that the source of a plant's energy is the sun, not fertilizer.

Region of origin

Japanese Jasmine’s native range is Eurasia, Africa, and Oceania.
