What does Phlox look like?
Phlox plants range from upright, tall forms to low, mat-like ground covers. Their flowers are small but often grow in dense clusters, with five petals and a tubular base. Colors include pale blue, violet, pink, bright red, and white. Many species have a light, pleasant scent. The foliage varies from narrow to broader leaves depending on the species, and some types form woody stems as they age.
Where does Phlox come from?
Phlox is native mainly to North America, with a single species found in Siberia. The genus name comes from the Ancient Greek word for 'flame', referring to the vivid colors of some species. Phlox have adapted to a range of habitats, from alpine tundra to open woodlands and prairies. Creeping phlox was introduced to gardens by the late 1700s, and various species have since become popular ornamentals.
When and how Phlox blooms
Phlox blooms at different times depending on the species: some in spring, others in summer or autumn. They grow best in conditions matching their native habitats: sun and well-drained soil for low-growing types, partial shade and moist soil for woodland species, and rich, moist soil for taller forms. Phlox can be grown from seed, stem cuttings, or by dividing clumps. Gardeners often space them out for air flow and remove spent flowers to prolong blooming.
How Phlox is used
Phlox is widely grown in gardens for its colorful and abundant flowers. It is valued for attracting butterflies and sometimes used as ground cover, especially the creeping types. Some species are grown as cut flowers. The foliage serves as food for the larvae of certain moths and butterflies, and the plants are also eaten by animals like rabbits and deer.
Kinds of Phlox
The genus includes upright species like Phlox paniculata (garden phlox), which is native from New York to Iowa and south to Georgia, Mississippi, and Arkansas. Creeping forms such as Phlox subulata (moss phlox) are used as ground cover and bloom in spring. Woodland species like Phlox divaricata prefer shade and moist soil. Most cultivated phlox are perennial, except for Phlox drummondii.
