The Madagascar Jasmine thrives with bright but indirect lighting. A bright North or East window is perfect,or any indirect light window. Also, try to provide some humidity as this plant will do better then although this is not critical for the plant's survival. The Madagascar jasmine is a vine with twining growth habit so you need to provide a support for it. One important point to remember is to not move the plant when in bloom, not even twist it around in the window as then the buds may fall.

The flowers are oftened used in Wedding Bouquets

Temperature
The temperature should be moderate 60-85F (16-28C), preferable at the cooler end during the rest period. Temperatures below 40F (7C) should be avoided.

Watering
Even watering throughout the growth season, March - September, especially if your plant is in bud or bloom. Keep somewhat on the dry side during the rest period.

Feeding
Feed with a fertilizer suitable for tropical plants during growing season. I use a 20-20-20 fertilizer with excellent result.
