Stephanotis is a tropical flowering vine that is desirable for its masses of white flowers and pleasing fragrance. Native to Madagascar, the plant is often called the "wedding vine" because its flowers are used in bridal bouquets. They also sometimes are called "Madagascar jasmine." Stephanotis plants are members of the milkweed family and need specific conditions in order to grow well and bloom. If such conditions are met, they can reach up to 15 feet in height and width, according to information published by North Carolina State University.
Choose a location that receives at least some sunlight each day, but not direct afternoon sunlight, which can be too intense for the plant, especially in hot climates. A location that receives morning sun followed by dappled afternoon shade is ideal.
Use moist, rich soil for your stephanotis. Most vines grow best in soil that is slightly damp and is high in organic matter, according to information published by the University of Missouri, and stephanotis is no exception. The soil should also be well-draining, as too much water in the soil can lead to root rot.
Provide support for your vine. This might be a free-standing trellis or one attached to a wall. It could even be a fence. Stephanotis will grow and climb quickly, according to information published by North Carolina State University.
Dig a hole deep and wide enough to accommodate the roots of the vine. The roots should be spread out slightly so that they just touch the sides and bottom of the hole. They should not have to be bent in order to fit comfortably inside the hole. Place the plant in the hole and backfill it with the soil you just removed. Water thoroughly, and give it one application of a balanced 10-10-10 water-soluble fertilizer according to the directions on the label.
Mulch around the stephanotis to keep moisture in and stifle weed growth. When the vine is large enough, gently train it onto the trellis. If the vine does not attach itself, help it along by tying it with soft pieces of cloth to the support structure.
