Overview & Character

Arabian Jasmine is grown for its scent, and the scent genuinely is remarkable — waxy white flowers that release their perfume most strongly in the evening and early morning. It is the national flower of the Philippines, where it is called sampaguita, and it is the jasmine used to scent tea.

As bonsai it is a scrambling shrub rather than a natural tree form, which means the work is in building and maintaining structure. It flowers on and off through the warm season rather than in one flush, so a healthy plant in good light gives you scent repeatedly rather than for two weeks in spring.

Identification

Foliage: Opposite, simple, glossy dark green leaves, elliptical to ovate, roughly 4–10 cm. Smooth and hairless — this is the key difference from Downy Jasmine.

Growth habit: Shrubby and scrambling; will climb if given support.

Flowers: White, waxy, intensely fragrant, five to nine petals, in clusters of three to twelve at shoot tips. Continuous in warmth.

Look-alikes:

Climate & USDA Zone

Zones 9–11 outdoors year-round. Elsewhere, outdoors in summer and indoors in winter. It wants warmth and humidity — 65–90°F is the comfortable band — and begins to decline below about 55°F. It has no frost tolerance whatever.

Light

Bright light, with four to six hours of direct sun ideally. Morning sun with afternoon shade suits it well in hot climates. Indoors, a south-facing window; in a dim room it will survive and simply not flower, which rather defeats the purpose.

Watering

Let the surface dry slightly, then water thoroughly. Keep it evenly moist without ever letting the mix stay soggy — this species is specifically noted as sensitive to overwatering, and root rot is its commonest cause of death.

Slightly drier conditions actually improve flowering. Underwatering, on the other hand, suppresses it. The target is damp and airy, checked often rather than watered on a schedule.

Soil & Root Care

Well-draining, loamy, slightly acid to neutral. A fast-draining bonsai mix reduces the rot risk considerably. Repot every two to three years in spring, and resist the urge to move it into a much larger pot — it dislikes excess soil volume around its roots, which stays wet and works against it.

Feeding

Feed monthly through the warm growing season with a balanced fertiliser. A high-phosphorus feed supports flowering. Stop or reduce sharply in winter when growth slows and light is short.

Pruning & Styling

Timing matters. Prune to shape immediately after a flowering flush finishes — late summer into early autumn for the main cut. Pruning in late winter risks removing the buds that would have given you the first flush of the year.

Cut just above a node. Through the season, pinch extending shoots to keep the scrambling habit under control and to build structure. Because it flowers repeatedly rather than once, light frequent trimming costs you less than one hard annual cut.

Propagation & Cuttings

Ease: Easy. Best methods: semi-hardwood cuttings; air-layering.

Semi-hardwood stem cuttings root readily in warm humid conditions. Air-layering also works well. Both preserve the parent's form and flowering habit.

Pests

Aphids, spider mites, whiteflies, mealybugs and scale — the full indoor set, and all of them worse in dry heated air over winter. Inspect leaf undersides weekly through the heating season.

Disease, Fungus & Infection

Root rot from overwatering is the dominant problem. Fungal leaf spotting occurs where foliage stays wet with poor air movement. Improve drainage and airflow before reaching for chemicals.

Most Common Causes of Death

1. Overwatering and root rot. The documented number one. This species is specifically noted as sensitive to soggy soil. 2. Cold. Decline below 55°F, death from frost. A close second, and often the finishing blow after a wet winter has weakened the roots. 3. Winter pest collapse. Mites and whitefly in dry indoor air. 4. Poor light. Not usually fatal, but it removes the flowering, which is the entire point of the plant.

Toxicity, Safety & Handling

The ASPCA lists true Jasminum species as non-toxic to dogs, cats and horses. One caution: the common name "jasmine" is attached to several unrelated and genuinely poisonous plants — Carolina jessamine (Gelsemium sempervirens) in particular. That rating applies to the genus Jasminum, not to everything called jasmine.
