    Regular deadheading will encourage vigorous flowering and keep plants shapely. Some sources recommend only full sun, while others say the color fades in full sun, and is better in partial sun. In tropical or sub-tropical zones, these survive all year as evergreen perennials and develop shrubbier habits.
