How to Grow and Care for Madagascar Jasmine

Madagascar jasmine (Stephanotis floribunda) is a popular houseplant with vining growth, glossy green leaves, and clusters of fragrant, star-like white flowers. Its powerful scent makes it a frequent addition to wedding bouquets, where it is sometimes called the bridal wreath. Despite its common name, this plant is not a true jasmine. The plant is mildly toxic if ingested and should be placed with care in homes with pets or small children.

Madagascar Jasmine Care Guide

Light

Madagascar jasmine flourishes in bright, indirect sunlight, such as from an east-facing window. While it needs plenty of light to produce flowers, direct afternoon sun can scorch the leaves. If grown outdoors, provide a location with dappled sunlight or protection from harsh midday rays. An indoor windowsill is suitable, but you may need to filter the light if it becomes too intense.

Soil

A well-draining, peat-based potting mix is recommended for this plant. This medium retains moisture without becoming waterlogged, a condition that can lead to root rot. Commercial mixes containing loam, peat moss, and perlite create an ideal balance of moisture retention and drainage. A container with drainage holes is required to allow excess water to escape.

Water

Watering must be adjusted based on the season. During the active growing season of spring and summer, water thoroughly whenever the top inch of soil feels dry. In fall and winter, the plant’s growth slows and its water needs decrease, so watering should be reduced. Always allow the pot to drain completely after watering to prevent the roots from sitting in water.

Temperature and Humidity

As a native of Madagascar, Stephanotis floribunda prefers warm and humid conditions, with a consistent temperature around 70°F (21°C). The plant is not frost-tolerant and must be protected from cold drafts. You can increase humidity by misting the foliage with tepid water every few days or by placing the pot on a tray filled with pebbles and water.

Fertilizer

During spring and summer, feed the plant every few weeks with a balanced, water-soluble fertilizer. A formula high in potassium, such as a tomato feed, is effective for encouraging blooms. Cease fertilizing in the fall and winter when the plant enters its dormant phase.

Pruning and Supporting Your Vine

Pruning is best performed after the main blooming period to control the plant’s size and remove dead stems. This encourages new growth, leading to a fuller appearance and more flowers the following season. Use clean, sharp shears for precise cuts.

As a natural climber, the plant requires a structure to cling to. Provide a trellis or stakes to allow the twining stems to grow upwards, preventing them from becoming a tangled mass. You may need to gently tie new stems to the support to guide their upward growth.

Encouraging Fragrant Blooms

Getting the plant to bloom reliably requires providing a “winter rest” period. This cool, drier phase triggers the plant to set flower buds for the upcoming season. Without this rest, the plant may fail to produce flowers.

For four to six weeks during winter, move the plant to a cooler location between 55-65°F (13-18°C). During this time, also significantly reduce watering, allowing the soil to become drier than usual. This dormant cycle encourages a robust display of blooms when regular care resumes in the spring.

Solving Common Issues

Yellowing Leaves

Yellow leaves often signal a problem with your watering routine. The most frequent cause is overwatering, which can lead to root rot. However, consistently underwatering the plant can also cause leaves to turn yellow and drop. Review your watering practices if you notice this issue.

Common Pests

Madagascar jasmine is susceptible to mealybugs and scale insects. Mealybugs appear as small, white, cottony masses, typically found in the crevices where leaves meet the stem. Scale insects look like small, brown bumps on the stems and undersides of leaves. Both pests feed on the plant’s sap and can be managed by dabbing them with a cotton swab dipped in rubbing alcohol or by using horticultural soap.

Failure to Bloom

If a healthy plant fails to flower, a specific care need is likely not being met. The most common reason is the absence of a cool, dry winter rest period. Other factors include insufficient light or incorrect fertilizer. Reviewing your care practices for these conditions can often resolve the issue.
