Tabernaemontana divaricata aka Crape Jasmine

Tabernaemontana divaricata typically reaches 1.8 to 3 meters (6-10 feet) in height with a spread of 0.9 to 1.8 meters (3-6 feet). The shrub forms a densely leafy, dome-shaped crown through its characteristic dichotomous branching pattern. Growth rate is moderate, and the plant maintains an attractive rounded form with branching starting close to the ground.

Tabernaemontana divaricata is native to South and Southeast Asia, with its natural range extending from the Himalayan foothills through India, Bangladesh, Nepal, Myanmar, Thailand, Cambodia, Laos, Vietnam, and into southern China (Yunnan). The species thrives in humid tropical and subtropical forests at elevations up to 1500 meters.

Tabernaemontana divaricata performs best in acidic to slightly acidic soil with a pH of 4.5 to 6.5. It tolerates various soil types including clay, sand, and loam, but requires well-draining conditions. In alkaline soils, the plant needs frequent fertilization to compensate for nutrient availability issues. Rich, organic soil that retains moisture without becoming waterlogged is ideal.

Tabernaemontana divaricata thrives in moderately humid conditions, reflecting its tropical and subtropical origins. In its natural habitat, it grows in areas with 800 to 2500mm annual rainfall. When grown indoors or in drier climates, the plant benefits from regular misting or placement near other plants to maintain adequate humidity levels around its foliage.

Apply a balanced fertilizer with an N-P-K ratio of 10-10-10 every 4 to 6 weeks during the growing season to promote healthy growth and flowering. Plants in alkaline soil require more frequent fertilization to maintain vigor. Monthly applications during the active growing season work well, and fertilization can be reduced in winter when growth slows.

The most reliable method is stem cuttings taken during the growing season (June to September). Cut 4-6 inch sections from healthy, non-flowering stems with several leaves. Root in a peat and perlite mixture at 77°F (25°C), and roots typically develop within 20-30 days. Air layering is also effective. Seeds can be used but germination is slow (1-2 months) and the plant fruits sparingly.

Tabernaemontana divaricata thrives in temperatures between 20-32°C (68-90°F) and requires temperatures above 10°C (50°F) for optimal growth. The plant can tolerate brief exposure to temperatures as low as -2°C (28°F) but is notably sensitive to frost. Extended cold periods will cause damage, so protection is needed in areas that experience frost.

Tabernaemontana divaricata responds well to pruning and can be shaped as a hedge, standard, or maintained as a compact shrub. Prune after flowering periods to maintain shape and encourage bushier growth. The plant's natural dichotomous branching creates an attractive form, so major pruning is typically only needed to control size or remove dead wood. When pruning, be aware that stems exude milky latex which can be irritating.

Repot Tabernaemontana divaricata every 2-3 years or when roots begin to circle the container. Spring is the ideal time for repotting. Choose a pot only slightly larger than the current one and use well-draining, acidic potting mix. The plant performs well in containers and can be maintained at manageable sizes through regular repotting and root pruning if needed.

The flowers are stunning waxy white blooms with five petals arranged in a characteristic pinwheel formation. Each flower measures 3-5 cm in diameter with ruffled or crimped edges. Blooming occurs year-round with peak flowering during warm months, and flowers often appear in clusters. The double-flowered cultivar 'Flore Pleno' is particularly popular for its fuller appearance.

Yes, Tabernaemontana divaricata produces an exquisite fragrance that intensifies at night. The soft, sweet scent is one of the plant's most appealing features and is reminiscent of jasmine, which contributes to its common names 'Crape Jasmine' and 'Cape Jasmine.' The nocturnal fragrance serves to attract moth pollinators and makes the plant particularly delightful in evening gardens.

The most popular cultivar is 'Flore Pleno' (also known as 'Double Flower'), which features densely doubled flowers with multiple layers of petals, creating a fuller, more rose-like appearance. The single-flowered wild type with its distinctive pinwheel form is also widely cultivated. Both forms produce the characteristic fragrance and are valued for their ornamental appeal.

Yes, in USDA zones 10-11, Tabernaemontana divaricata grows excellently outdoors year-round. It's not considered invasive and is recommended for landscape use in South Florida and similar climates. In cooler zones (9b with protection), it can be grown outdoors but requires frost protection. In temperate climates, it's best grown in containers that can be brought indoors during winter.

Tabernaemontana divaricata is generally pest-resistant with few serious problems. Occasional pests include scales, mites, and nematodes, which may cause sooty mold as a secondary issue. However, UF IFAS notes that long-term plant health is usually not affected by pests. No major diseases are of concern. The plant's milky latex may provide some natural pest deterrence.

During spring and summer (active growth), provide regular watering and monthly fertilization for best flowering. The plant blooms year-round but flowers most heavily during warm months. In fall and winter, reduce watering frequency and stop fertilizing. In cooler climates, bring container plants indoors before temperatures drop below 10°C (50°F). The plant remains evergreen and doesn't have a true dormancy period.

The glossy, dark green leaves benefit from occasional cleaning to maintain their attractive appearance and optimize photosynthesis. Gently wipe leaves with a damp cloth to remove dust. Avoid using leaf shine products as they can clog pores. The plant naturally sheds old leaves, so remove any yellowed or dead foliage to maintain appearance and prevent pest issues.

Yellow leaves on Tabernaemontana divaricata often indicate chlorosis from alkaline soil conditions, as the plant prefers acidic soil (pH 4.5-6.5). Other causes include overwatering leading to root problems, underwatering, nutrient deficiencies (especially iron in alkaline soils), or natural leaf aging. Test soil pH and adjust if necessary. Increase fertilization frequency if growing in alkaline conditions.

Brown leaf tips or edges typically indicate insufficient humidity, underwatering, or salt buildup from fertilizers. Brown spots may result from fungal issues or cold damage. The plant is sensitive to frost and temperatures below 10°C (50°F) can cause browning. Ensure consistent moisture, adequate humidity, and protect from cold temperatures. Flush soil occasionally to reduce salt accumulation.

Drooping leaves and stems usually indicate water stress—either too much or too little. The plant requires consistently moist (not waterlogged) soil. Check soil moisture and adjust watering accordingly. Other causes include root rot from poor drainage, heat stress, or transplant shock. Ensure the pot has drainage holes and the soil isn't compacted. Recovery typically occurs once proper moisture levels are restored.

Tabernaemontana divaricata has extensive use in traditional Indian medicine systems including Ayurveda. Various plant parts (roots, leaves, flowers, latex) have been used traditionally to treat eye ailments, skin diseases, wounds, fever, pain, and hypertension. The plant contains numerous indole alkaloids (coronaridine, voacangine, ibogamine) currently under pharmacological investigation. However, due to its toxicity, internal use should only be under qualified medical supervision.

Beyond its ornamental value, Tabernaemontana divaricata has several traditional uses. Historically, the toxic latex was used to poison arrows. The plant serves as a fuel source in some regions. In Indian culture, the fragrant white flowers hold religious significance and are used in temple offerings. Its continuous flowering and pleasant fragrance make it popular in evening and fragrance gardens.

If you're looking for a plant that offers a moderate level of challenge, Crape Jasmine is a great choice to test your gardening skills.

Crape Jasmine should be watered regularly, allowing the soil to dry out between waterings.

Crape Jasmine requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Crepe Jasmine is always in the right place to thrive.
