The yellow jasmine

Information and botanical notes

Yellow jasmine is a shrubby plant belonging to the Jasminum genus. Its scientific name is Jasminum nudiflorum, also known as St. Joseph’s jasmine. Originally from China, it is now cultivated in a large part of the West, thanks also to its incredible resistance to low temperatures. The branches are long and tapered, dark green in color, and often appear superimposed and closely intertwined with each other. The leaves are small, oval and leathery in nature, also dark green in color and joined in number of three elements along the branches. The yellow jasmine renews its leaves each year, so it is a deciduous plant. The flowers are small, yellow and with six petals. This plant grows remarkably and can easily exceed 3 meters in height.

The peculiarity of this species lies mainly in the flowering. In fact, yellow jasmine does not bloom in midsummer like other plants, but at the end of winter. After a few months from the loss of the leaves, small yellow flowers appear on the bare twigs (usually towards the end of February and the beginning of March), which persist for a long time until late spring. Flowering occurs almost in unison and, especially in very thick hedges, the resulting effect is one of the most sought after by enthusiasts and gardeners. The epithet «nudiflorum» of the scientific name indicates precisely the flowering of the species, which occurs when the plant is now stripped of its leaves. Yellow jasmine fits very well both in the garden and in pots and needs simple care for it to produce flowers.

Plant the yellow jasmine

Yellow jasmine adapts to any corner of the garden, whether it is exposed to the sun or in the shade. However, it is good to remember that plants exposed to light produce more flowers. This plant also reproduces by cuttings and the best time to plant it is autumn, in small pots protected from the elements. The growing substrate must be rich in nutrients, therefore there is a need for the frequent use of special fertilizers (on the market there are some products specifically indicated for jasmine) and good drainage, through the use of pozzolan or expanded clay. . Watering must be sporadic and essentially limited to periods that are too hot, since yellow jasmine lives well with rainwater alone. The parasites that mainly attack jasmine are cottony mealybugs and some species of fungi of the genus Uncinula, which cause powdery mildew, a disease that causes a whitish film on the leaves. To prevent these attacks, it is necessary to be careful of humidity and water stagnation on the leaves and on the ground, using special products if necessary.


Once the yellow jasmine has been placed in the garden, the growth of the plant is decided. Being a good climber, this species adapts both to grow along surrounding walls or gates, or to descend in bundles from balconies. In spring, dry or compromised branches are eliminated and the remaining ones shortened by about 70-80%. The pruning operations must be carried out when our plant has reached one year of life, and exactly one year after having planted it in the garden. Much attention must be paid to the method of the cuts; they must be clean and without imperfections, to avoid the death of the branch or attacks by external parasites. Pruning is necessary both to thicken the plant more and to allow it to grow appropriately in relation to the place where it was planted.
