Overview
Night-Blooming Jasmine is a fast-growing evergreen shrub whose slender greenish-white flowers release an intense fragrance after sunset. It offers a dramatic sensory feature but needs careful placement because of scent and toxicity.
Mature Size and Habit
Unpruned plants can reach 8 to 12 feet tall with a broad arching spread. Multiple stems create a large informal screen, and frequent light pruning is usually required to keep the shrub within a residential bed.
Best Landscape Uses
Use it as a background shrub or privacy screen in a warm, protected location. Keep it away from bedroom windows, compact patios, air intakes, play areas, and narrow walks because the nighttime fragrance can become overpowering.
Sunlight
Full sun promotes dense growth and strong flowering. Partial sun also works in Tampa, especially with morning light. Heavy shade encourages lanky stems, fewer flowers, and a plant that reaches beyond its allotted space.
Soil, Drainage, and Irrigation
Plant in moderately fertile, well-drained soil. Water deeply during establishment, then provide moderate irrigation during dry weather. Avoid soggy ground, but do not allow a newly installed root ball to dry completely.
Best Planting Season for Tampa and Central Florida
Fall through spring allows roots to establish before peak heat. Warm-season planting is possible with close watering. Choose the final location before installation because a mature shrub becomes large and difficult to relocate.
Pruning and Maintenance
Prune after a flowering flush and remove crossing or weak stems from the base. Deadhead or remove berries where practical. Monitor for whiteflies, scale, mites, sooty mold, and rapid regrowth after hard pruning.
Wildlife Value
Night-opening flowers may attract nocturnal pollinators, and the dense canopy provides limited shelter. Because the berries and other plant parts are toxic, it should not be promoted as a wildlife-food plant in a residential landscape.
Cold and Heat Sensitivity
Tampa heat and humidity support rapid growth. Frost burns leaves and young stems, while a hard freeze can cause major dieback. A sheltered site improves winter appearance, and established roots often resprout after light cold damage.
Safety, Roots, and Placement Warnings
All plant parts, especially fruit, should be treated as poisonous to people, pets, and livestock. Strong fragrance can trigger headaches or respiratory irritation in sensitive individuals. Keep the plant out of reach and away from enclosed sitting areas.
Invasive Concerns
Cestrum nocturnum is nonnative and invasive in several warm regions. Remove berries before seed matures, control volunteers promptly, and avoid planting beside natural areas, waterways, or places where birds can move seed beyond the maintained landscape.
