Culture Notes
These plants are usually grown as annuals in cooler zones, but can be perennials in frost free areas.  Flowers can be left on these plants, but removing them will help the plant maintain its bright foliage. Once plants begin to flower, even the new shoots that develop after pinching produce flowers. This signals that it is time to begin thinking about replacing the plants with new ones. The foliage of Coleus plants looks great when arranged with freshly cut flowers.
