Jasminum sambac is an evergreen shrub that is widely grown throughout the tropics. This attractive ornamental shrub bears dark green foliage and powerfully fragrant white flowers, which only bloom at night. The oil that is extracted from the blossoms forms a base for some of the world's most popular fragrances. When given proper care, the jasminum sambac will remain in bloom for six to nine months out of the year, allowing you to pluck to your heart's content.
Determine your United States Department of Agriculture hardiness zone (see Resources). To successfully grow jasminum sambac outdoors, you must live in a zone 8 or higher. As is common in tropical plants, jasmines thrive in hot, humid daytime environments. They can be killed by frost.
Choose a planting site for your jasmine. This shrub grows fast and tolerates shade well, so select a location where you can appreciate the full decorative effect of the deep green leaves or where you can take in the fragrance of the jasmine flowers in full bloom.
Prepare the soil for planting by working in a large quantity of organic material, such as peat moss or compost. Ensure your planting site is moist but well drained. Jasmine sambac does not cope well with clay-like soil or boggy conditions.
Apply a general purpose fertiliser once a month from March through November. Water when the soil is dry, being careful not to give the plant too much water.
Tie new growth to a trellis or establish another system of support. The branches of an average jasmine sambac shrub have been known to reach 8 feet in length, and you may wish to guide the general direction of this growth.
Prune your jasmine diligently once it has bloomed. The fragrant flowers will only last for one day once they have opened their petals. Regular trimming will help encourage the growth of new wood, and only new growth will produce more flowers.
On the evening in which they bloom, the flowers of the jasmine sambac plant can be plucked and used to create your own sweet-scented perfume.
The jasmine sambac will grow well indoors in a large container, but the fragrance of the flowers can be overwhelming to some.
