Sri Lankan Jasmine (Wrightia Antidysenterica)
When the Sri Lankan Jasmine (Wrightia antidysenterica) is in full bloom, it earns every one of its common names — Snowflake, Milky Way, Arctic Snow. The compact, bushy shrub covers itself so completely in pure white, five-petalled star flowers that the green leaves beneath almost disappear. It blooms not once a season but continuously, year-round in India's tropical climate, pausing only briefly between flush cycles. Each flower is 2.5–3.5 cm across, white with a small frilled corona at the centre, arranged in loose clusters at the branch tips — and the whole display attracts butterflies in numbers that make it one of the finest pollinator plants for Indian gardens. The name tells an older story: Wrightia honours William Wright, the 18th-century Scottish physician-botanist; antidysenterica records the plant's historical use against dysentery — its bark a remedy in traditional medicine across South Asia for centuries. A plant with a past, and one of the most rewarding flowering shrubs for any Indian garden, balcony, or terrace.
Light
▾
Full sun — at least 6–8 hours of direct sunlight daily is essential for continuous, abundant flowering. A south or west-facing open garden position, balcony, or terrace is ideal. The plant tolerates partial shade but flowering reduces noticeably — in deep shade it blooms rarely and growth becomes sparse and leggy. This is not an indoor plant; it is an outdoor sun plant that happens to suit containers beautifully on a bright terrace.
Watering
▾
Water deeply 2–3 times a week in summer; reduce to once or twice a week in cooler months. Allow the top 2–3 cm of soil to dry between waterings — consistently moist but never waterlogged. In India's monsoon season, established garden plants need little to no supplemental watering; ensure drainage is excellent to prevent root rot from sustained heavy rain. Container plants need more frequent watering than in-ground plants in hot weather — check daily during peak summer.
Humidity
▾
Naturally suited to India's tropical humidity — no supplemental humidity required. Thrives equally well in humid coastal conditions and the drier climates of central and northern India. One of the most climatically adaptable flowering shrubs for the subcontinent. Ensure good air circulation around the plant to prevent fungal issues in very humid conditions.
Growing Media
▾
Well-draining, fertile loamy soil — standard garden soil amended with compost and coarse sand or perlite for improved drainage. pH 6.0–7.5. For containers, a quality potting mix with 20–30% perlite is excellent. Plant 3–4 feet apart for hedges. Repot container plants every 2 years in spring, moving up one pot size. Mulch the base of in-ground plants during summer to retain moisture and keep roots cool.
Feeding
▾
Balanced fertilizer (NPK 10-10-10 or similar) once a month during the growing season — spring through early autumn. A phosphorus-rich formula (such as NPK 10-30-10) applied once in early spring encourages heavier flower production. Apply to moist soil. Slow-release granules are a low-maintenance alternative, applied every 3 months. No feeding in winter. Do not over-fertilize with high nitrogen — it promotes lush foliage at the expense of flowers.
Flowering Slowing or Stopping
▾
Almost always caused by insufficient light or lack of post-flush pruning. Move to a position with at least 6 hours of direct sun and prune immediately behind spent flower clusters to trigger new branching. If the plant has not been pruned in a long time, a hard prune of one-third followed by a phosphorus-rich feed will typically restart vigorous flowering within 4–6 weeks.
Leggy Growth with Sparse Leaves
▾
Insufficient light and/or no pruning. Move to full sun and cut back leggy stems by one-third to one-half. New compact branching with dense foliage and more flower tips will emerge within a few weeks in good light.
Leaf Drop or Semi-Deciduous Behaviour
▾
Normal during dry or cool periods — the plant is naturally semi-deciduous and may drop some leaves in response to drought or temperatures below 15°C. Resume regular watering as temperatures warm and new growth will flush quickly. Not a sign of serious distress unless accompanied by root rot symptoms.
Root Rot — Yellowing Leaves, Waterlogged Soil
▾
Poor drainage — the most common problem, particularly during the monsoon season for in-ground plants in clay-heavy soil. Ensure excellent drainage at planting. For container plants, move to shelter during sustained heavy rain or ensure the pot drains freely. Allow to dry slightly and improve drainage before resuming normal watering.
Aphids or Spider Mites
▾
Occasional but uncommon — this plant is notably pest-resistant. Treat aphid clusters with a strong water jet or diluted neem oil spray. Spider mites in very dry conditions: boost humidity around the plant and treat with insecticidal soap every 5–7 days for 3 weeks. Scale: isopropyl alcohol on a cotton swab for small infestations.
