Light and lighting requirements
The Passionflowers require direct sunlight for several hours a day for proper growth and to ensure lush flowering. In spaces with insufficient light, flowering will be poor, and the plant will tend to weaken or develop yellow leaves. If you'd like more information about growing them in different environments, we recommend visiting indoor climbing plants.
