The Madagascar jasmine ( Stephanotis floribunda ), also known as wax jasmine, is one of the most prized plants for those seeking an exotic climber with extraordinarily fragrant white flowers. Native to the island of Madagascar, it stands out for its elegant form, evergreen foliage of intense, glossy green , and abundant blooms that adorn balconies, terraces, and bright indoor spaces. Below, discover how to care for your Madagascar jasmine in detail so that it remains healthy and spectacular for years to come.
Botanical and ornamental characteristics of Madagascar jasmine
Stephanotis floribunda is a perennial climbing vine belonging to the Apocynaceae family. In its natural habitat, it can reach over 10 meters in height, although in domestic cultivation it is usually limited to 3-5 meters, depending on the available space and growing conditions. Its leaves are leathery, oval, waxy in texture, and a glossy dark green, providing dense coverage year-round. It clings to supports, walls, or arches using its flexible stems, forming attractive vertical structures.
The flowers are white, tubular, and grow in clusters. They are characterized by their sweet, intense, and exotic fragrance. They bloom primarily from spring until early autumn, although in ideal conditions, they can continue flowering for several months. Learn more about Madagascar jasmine at this link.
Another unique feature of the Madagascar jasmine is the way its flowers have five waxy petals, in addition to its production of fruits similar to small pods if pollination has been successful, although this is less common in domestic cultivation.
Where to find Madagascar jasmine
Due to its tropical origin, the Madagascar jasmine requires mild temperatures and a warm environment year-round . The ideal temperature for its growth is between 18°C and 25°C. It does not tolerate frost and can be damaged if exposed to temperatures below 10°C for extended periods. It can withstand brief drops to 5°C, but this is not recommended.
Because it is very sensitive to cold, in regions with harsh winters it is best to grow it indoors , in well-lit rooms away from drafts. In warm, frost-free climates, it can be kept outdoors year-round. In any case, always ensure a bright environment with plenty of indirect natural light . Madagascar jasmine requires a lot of light to bloom fully, but you should avoid direct, strong sunlight, especially during the hottest hours of the day, as its leaves can burn.

It can tolerate some mild sun for one or two hours during less intense periods, but it's always preferable to provide bright shade. Many people choose to place it next to an east-facing window or behind a curtain to achieve a balance of light and shade.
Regarding humidity , Madagascar jasmine thrives in humid environments, as dry air (especially from indoor heating) can negatively impact the health of its leaves and buds. If the air is dry, mist the plant with rainwater or distilled water (avoiding wetting the flowers) or use a nearby humidifier. Placing the pot on a saucer filled with damp pebbles helps, but never allow the bottom of the pot to become waterlogged.
How to water and maintain humidity
Watering Madagascar jasmine requires attention and balance. As a tropical plant, it needs consistent moisture in the soil , but it's crucial to avoid waterlogging. Excess water can cause root rot, while drought will stunt its growth and flowering.
- FrequencyDuring the warmest and most active months (spring and summer), water every 2-3 days if the substrate dries out quickly. In fall and winter, reduce the frequency to once a week or when you notice the top layer of the substrate is dry.
- Water quality: Use soft water, rainwater or bottled water, avoiding tap water if it is very hard, as it can cause yellowing of leaves. Know the meaning of the jasmine flower.
- how to waterPour water slowly over the soil until it runs lightly through the drainage holes. If the pot has a saucer, empty it after a few minutes to prevent standing water.
During its flowering stage, the Madagascar jasmine requires increased humidity. Maintaining high ambient humidity is crucial. Mist the leaves (not the flowers) several times a week if the air is dry. If the plant is near heating or air conditioning, these routines become even more important to prevent bud drop and leaf drying.
The ideal substrate and transplant
The substrate is key to the proper development of Madagascar jasmine. This plant requires a high-quality, nutrient-rich, light mix with excellent drainage . A recommended option is to use a universal potting mix enriched with perlite, peat moss, and some coarse sand. This ensures aeration and prevents soil compaction, which would hinder root growth and could cause problems due to excess moisture. Discover which jasmine is the most fragrant.
Adding organic matter like worm castings or mature compost is beneficial to encourage growth and increase water retention without overwatering. Before planting, always ensure the pot has sufficient drainage holes.
Transplanting is best done in early spring, when the plant awakens from dormancy. It's usually sufficient every 2-3 years, or when you see roots emerging from the bottom of the pot. Choose a container only slightly larger (5-10 cm wider and deeper) than the previous one to avoid overwatering of the remaining potting mix.
Fertilizing: how and when to do it
Madagascar jasmine benefits from regular fertilization during its peak growing season . Apply a liquid fertilizer for flowering plants or a balanced fertilizer specifically formulated for jasmine every 15 days, from early spring until the end of summer. This will boost flower production and the plant's overall vigor. Stop fertilizing in autumn and winter, when growth slows or stops. Follow these tips for beautiful jasmine plants.
It's recommended to use liquid fertilizers dissolved in the irrigation water, as they are absorbed quickly and are more difficult to overdo. There are also controlled-release fertilizer cloves, which are placed in the substrate and provide nutrients gradually. For outdoor and soil crops, well-fermented manure, worm castings, or mature compost can be used in spring.
Pruning Madagascar jasmine
Pruning is essential for climbing plants, especially Madagascar jasmine, which can grow excessively if it finds optimal conditions. The main purpose of pruning is to control size, promote a compact structure , remove damaged branches, and encourage flowering.
- When to prune: Perform the main pruning after flowering, in late summer or early fall, adjusting the size of the plant and removing stems that are aged, damaged, or have pests.
- Formation pruning: When the plant is young, guide the main stems around the chosen tutor or structure, supporting them without drowning them.
- Maintenance pruning: Remove dry leaves, withered flowers and weak branches periodically to maintain the plant's good appearance and prevent problems.
Keep in mind that Madagascar jasmine blooms on old wood , meaning on stems that developed the previous season. Therefore, excessive pruning in late winter could reduce the year's flowering. Avoid pruning too much just before bud formation. Climbing plants can also help you decorate outdoor spaces.
reproduction and multiplication
Madagascar jasmine can be propagated by seed (very difficult and uncommon) or by semi-hardwood cuttings during spring or summer. To do this:
- Cut a healthy stem about 10-15 cm long, with at least two nodes and a couple of healthy leaves.
- Remove the lower leaves and dip the base in powdered rooting hormones.
- Plant the cutting in a light, moist mix of peat and sand, and cover it with a clear bag or in a mini greenhouse to maintain humidity.
- Place the container in a warm, bright location, avoiding direct sunlight. With stable humidity and temperature, rooting can occur in 4-8 weeks.
Common problems: yellow leaves, bud drop, and pests
Improper care of Madagascar jasmine can lead to easily recognizable symptoms:
- Yellow sheets: This is usually due to a lack of light, overwatering, or using hard water with a high limescale content. Move the plant to a brighter location, check watering frequency, and use soft water.
- Lower leaves discolored or drooping: This may be related to a nutrient deficiency or the use of depleted substrate. Apply specific liquid fertilizer during spring and summer.
- Dry buds or bud dropThis occurs if the plant is repeatedly moved from one flowering location to another, if the ambient humidity is low, or if there is a lack of water. Keep the plant stable, water regularly, and ensure a humid atmosphere in the room.
- common pests: It is susceptible to attacks from mealybugs, aphids and mites, especially in dry environments. Periodically inspect the underside of leaves and apply specific treatments if you detect colonies. Manually removing mealybugs and washing the leaves with water can help as a preventative measure.
- Root rot: This occurs due to overwatering and poor drainage. If you see wilted leaves and blackened stems, let the substrate dry and remove any affected parts.
Flowering: how to enhance it and maintain its splendor
The Madagascar jasmine is famous for its long and fragrant flowering, but it is very demanding in terms of the conditions that stimulate it:
- Adequate lightWithout high levels of natural light, the plant will hardly flower. Ensure a well-lit environment and avoid heavy shade.
- Balanced irrigationKeep the substrate moist (not waterlogged) during flowering. Avoid allowing it to dry out completely or remain permanently soaked.
- High ambient humidity: Humidify the air by spraying the leaves or using a humidifier.
- Rest periodIn autumn and winter, the plant needs fewer hours of light, a slightly cooler temperature (never below 10°C), minimal watering, and no fertilizer. This "rest" is essential for the plant to recharge its energy and produce abundant blooms the following season.
- Avoid moving it when it is in bloom.: Move the plant as little as possible when it has buds, as they can easily come off.
The flowers are grouped in clusters, each with five waxy, glossy petals. Indoors, the scent can permeate the entire room.
Can you grow Madagascar jasmine outdoors?
Madagascar jasmine can only be grown outdoors if the climate is mild year-round and frost-free in winter. It's ideal for gardens in subtropical or warm temperate zones, where temperatures rarely drop below 10°C (50°F). Place the plant in bright shade or partial shade, protected from wind and direct sunlight. Discover how to transform your space with jasmine.
In areas where winters are cold, you can take it outside only in spring and summer , preferably without removing it from the pot so you can bring it back inside when the low temperatures return.
In garden soil, choose a well-drained area rich in organic matter and with support poles or pergolas where the plant can spread. Add powdered organic fertilizers such as worm castings or well-rotted manure each early spring to strengthen the outdoor plant.
Additional Tips for Healthy Madagascar Jasmine
