Song Of India "I love that it has a lot of color for an indoor plant," Monji says. "The bright yellow is a great mood lifter." The Song of India requires medium light and should sit on or near the sill of a north-facing window, or a few feet away from a window that gets east- or west-facing light. Water it moderately once per week, but more sparingly during the winter months. Indoors, the Song of India can get two to three feet tall after a few years.
