Phlox are herbaceous perennials that are simple to grow and maintain. That means they will come back year-after-year to provide you with a fantastic show of blooms come summer. They are great at attracting butterflies and other pollinators into the garden and need only a little annual maintenance. They are fairly drought-tolerant so don't need lots of watering, benefit from a mulching each spring, and want to be kept weed free. Apart from that, just deadhead throughout the season and annually cut back the stems to ensure the plants keep performing every year.
