Although peacock jasmine can only be grown outdoors in warm, tropical climates, it works very well as a houseplant. When properly cared for, peacock jasmine will be covered with masses of snow white flowers that will fill your home with sweet scent for most of the year. Also known as 'pikake,' peacock jasmine is widely grown in the Hawaiian Islands, where it's used to make leis and perfume.
Put peacock jasmine where it will get plenty of bright light, but don't put it directly in a window where it will get hot afternoon sunlight. Although peacock jasmine can grow in partial shade, it will produce fewer blooms with less light.
Keep peacock jasmine in a warm room. Temperatures between 80 and 90 are best, with nighttime temperatures between 70 and 80. Keep it away from cold drafts. If the nighttime temperatures drop below 60 degrees, the plant will temporarily stop blooming.
Allow the top of the soil to dry out, and then water it deeply and let the water run through the bottom of the pot. Never allow the bottom of the pot to sit in water. The plant will also benefit from a misting of room temperature water on dry winter days.
Prune peacock jasmine with pruners or household scissors between November and January when the plant isn't blooming. Clip off just enough to keep the plant the desired size and shape. Remove dead leaves as needed. Provide peacock jasmine with a wire hoop or trellis to climb on.
Fertilize peacock jasmine after pruning, and again two to three times spread out evenly during the year. Use a good quality liquid houseplant fertilizer.
