A strong-growing woody climber from Madagascar, having thickish elliptic leaves, and masses of highly fragrant waxy-white tubular flowers. Almost every grower of flowers for market or florist work at one time grew Stephanotis, and notwithstanding the severe competition from other beautiful white flowers of recent years, the blooms of Stephanotis still find a market. The plants are easily grown in a compost of loam and peat, and may be increased by layers or by cuttings of the half-ripened shoots. A stove temperature suits the plants best when growing freely, and abundance of water must be given at the root, and also by syringing the foliage. When in flower a lower temperature - about 65° F. - by night is sufficient. Scale and Mealy Bug are the worst enemies of the Stephanotis, but may be kept in check by syringing with insecticides occasionally and by fumigation or vaporizing. In winter, when the plants are dormant, it is sometimes necessary to untie the shoots and cut out the older wood. The plants may then be thoroughly cleansed if needed. One plant in the course of time will cover an enormous amount of space, and in some places the tips of the shoots are nearly 100 ft. from the main stem. The flowers which appear in early summer are bunched up in half-dozens for market, and are still popular for wreaths, crosses, wedding, and other bouquets.
