Phlox is a genus of flowering plants that belongs to the family Polemoniaceae. They are commonly known as "phlox" and are prized for their showy, fragrant flowers and attractive foliage. Phlox plants are native to North America, and are now grown in many other parts of the world as ornamental plants.

Phlox plants have upright stems that can reach up to three feet in height. The flowers are typically pink, purple, white, or red, and have five petals that are arranged in clusters or spikes. The foliage of Phlox plants is often green and can be quite ornamental, with lance-shaped or ovate leaves.
