Phlox stellaria, commonly known as starry phlox or moss phlox, is a flowering perennial plant that belongs to the Polemoniaceae family. It is native to North America and is highly valued for its vibrant, star-shaped flowers and low-growing, mat-forming habit.
Starry phlox typically reaches a height of 6-12 inches (15-30 cm) and spreads to form dense, moss-like mats. It features slender, needle-like green leaves that are arranged in whorls along the stems. The leaves are typically evergreen, meaning they persist throughout the year, providing some foliage even during the winter months.
The plant bears clusters of small, fragrant flowers that are typically blue, pink, or white in color. These five-petaled flowers have a star-like appearance, hence the common name "starry phlox." The blooms appear in early to mid-spring and continue into summer, attracting pollinators like butterflies and bees.
Phlox stellaria is a resilient, adaptable plant that is well-suited for various garden settings. It thrives in full to partial sun and prefers well-draining, slightly acidic soil. It is commonly used as groundcover, particularly in rock gardens, borders, or along paths, where its dense, spreading growth habit can create a lush carpet of color.
Overall, Phlox stellaria is a visually striking and versatile perennial plant, cherished for its star-shaped flowers, evergreen foliage, and ability to beautify landscapes with its low-growing, mat-forming nature.
