Both exotic looking and easy to care for, the passion flower (Passiflora incarnata) is one of the most interesting flowering vines around. This tropical vine can be easily grown indoors to create a beautiful tropical setting. Passion flowers grow best in bright light. Give your plant at least four hours of direct sunlight per day. Water the passion flower vine regularly during its growing stage and prepare a proper drainage. You can let them dry out a little in autumn and winter.
To keep your passionflower vines healthy and blooming, plant them in full sun to partial shade. Plants appreciate some afternoon shade in extremely hot climates. Passionflowers generally need at least four to six full hours of sunlight a day (or more in cooler climates).
