Phlox (pronounced /flɒks/ or "flocks"; from the Latin for a flame-colored flower, which is from the Greek φλόξ, meaning 'flame'; plural "phlox" or "phloxes") is a genus of 67 species of annual or perennialflowering plants. Some species flower in early spring while others flower in summer into fall. Most species are native to temperate North America but a few species are also from northeastern Asia. They are found growing in diverse habitats from alpine locations to open woodlands and prairies.
Phlox flowers range in color from pale blue to bright red to white. Some species such as Phlox glaberrima (Smooth Phlox) grow to 1.5 m tall, while others, such as Phlox stolonifera (Creeping Phlox), form low mats only a few centimetres in height.
Several species of phlox are commonly cultivated in gardens. Most cultivated phlox, with the notable exception of Drummond phlox, are perennial. Phlox cultivars are available in shades of white, purple, blue, pink, and yellow. Most are best grown in well-drained soil, exposed to partial shade to partial sun. Phlox are valued in the garden for their ability to attract butterflies.
