When not in bloom, Creeping Phlox (Phlox subulata) still maintains a visually appealing appearance. It forms a dense, ground-hugging mat of foliage. The leaves are small, needle-like, and evergreen, creating a lush carpet of green throughout the year. The texture is somewhat fine and can be quite dense, making it an excellent ground cover. The foliage tends to be quite tough and hardy, able to withstand different weather conditions.

The color of the leaves is typically a vibrant green, though some varieties may have a slightly bluish or grayish hue. The plant spreads outwards, covering the ground effectively. Without its blooms, Creeping Phlox won’t have the same vibrant splash of color it’s known for in spring, but its evergreen foliage still provides a consistent and attractive cover for rock gardens, borders, and garden paths.

In the UK, the ideal time to plant Creeping Phlox (Phlox subulata) is during the early spring or early autumn. This timing allows the plants to establish their roots in moderate temperatures, which is crucial for their growth and health.

  • Early Spring Planting: Planting in early spring, after the last frost, gives the Phlox a full growing season to establish. The cool but not too cold temperatures are ideal for root development.
  • Early Autumn Planting: Planting in early autumn allows the Phlox to establish before the winter. The soil is still warm from summer, which encourages root growth, but the cooler air temperatures are less stressful for the plants.

When planting, choose a spot with well-drained soil and full sun exposure, as Creeping Phlox thrives in these conditions. Prepare the organic soil by loosening it and adding organic matter if needed. Plant the Phlox at the same depth it was in the pot, spacing them about 15-20 cm apart to allow for spreading. Regular watering during the first growing season will help establish a strong root system.
