Botanical name: Jasminum polyanthum
Pink Jasmine also called Winter Jasmine, Star Jasmine, French Perfume or Chinese Jasmine is a vigorously growing climbing flowering houseplant which bears fragrant flowers in clusters. They are mainly grown for the characteristic fragrance of their flowers. Pink Jasmines require bright light, moist soil at all times and support for the stems. They can be grown on a trellis, in hanging baskets or even on fences. Pink Jasmine is native to southeastern China. There are several Jasmines that can be grown as houseplants. The most popular ones have white blooms with a delicious fragrance. The easiest one to grow is Jasminum polyanthum (Pink Jasmine) whose pale rosy buds open into starry white flowers borne in groups of 20 or more. It is a vigorous climber and the stems can reach 10 ft if left unpruned. It is rarely attacked by diseases and pests. Another common Jasmine is the Jasminum officinale (White Jasmine) which bears twining stems, much divided leaves and long-tubed white flowers with a strong fragrance. The odd one out is the Jasminum primulinum (Primrose Jasmine) whose flowers are yellow and non-fragrant, and the stems do not twine. The flowers are semi-double with 6 or more petals.

Keep the soil moist at all times for Pink Jasmine and allow the top 1-2 in. of soil to dry out between waterings. Reduce watering during the cold period. Avoid waterlogging as it can lead to Root-rot Disease. Learn more on how to water houseplants.
Average warmth between 18-240C during the growing season is ideal for Pink Jasmine. Keep it cool at about 150C during the dormancy period. Protect it from cold and hot draughts. Learn more on temperature for houseplants.
Average room humidity is ideal for Pink Jasmine. Mist the leaves regularly or set the pot on a wet pebble tray to raise humidity if the air is too dry.
Feed Pink Jasmine with a phosphorous-rich water-soluble fertilizer every 2-3 weeks during the growing season. Withhold feeding in the dormancy stage. Find out more on how to feed houseplants.
Repot Pink Jasmine once a year at the beginning of the growing season only when the plant is pot-bound. Pink Jasmine blooms best when slightly pot-bound. Use a pot 1 size larger and one that has a drainage hole to prevent waterlogging as it can lead to Root-rot Disease. The soil should be rich in organic matter and free-draining.
Pruning Pink Jasmine is easy. Remove dead flowers and leaves to maintain the plant neat and tidy. Pinch off the growing tips to encourage compact growth and prevent the plant from getting unruly. After flowering, cut back the stems to rejuvenate growth and to keep the plant compact. Learn more on how to prune houseplants.
