About this plant
Phlox subulata 'Emerald Blue', commonly known as Creeping Phlox, is a truly spectacular perennial groundcover renowned for its prolific spring bloom. From mid-spring to early summer, its dense, needle-like foliage becomes almost entirely obscured by a breathtaking display of small, star-shaped, periwinkle-blue flowers. This cultivar is a fast-growing, evergreen perennial that forms a lush, mat-like spread. It's an excellent choice for a variety of landscape applications, including rock gardens, slopes, pathways, and as an edger. Its tough nature makes it ideal for areas where other plants might struggle. Beyond its dazzling spring show, 'Emerald Blue' offers year-round attractive, moss-like foliage, providing continuous texture and color. It's a low-water, low-maintenance plant once established, making it a favorite for both novice and experienced gardeners seeking vibrant curb appeal.
Care & maintenance
Requires well-drained soil. Shear back lightly after flowering to encourage dense growth and potential rebloom. Fertilize sparingly in early spring with a balanced slow-release formula. Divide overcrowded clumps every 2-3 years in early spring or fall to maintain vigor. Generally pest and disease resistant.
