  • Botanical name: Phlox subulata
  • Common name: Creeping phlox
  • Family: Polemoniaceae

Phlox subulata is also known by its common names of creeping phlox or moss phlox, and is a popular and easily grown hardy plant for rock gardens, raised beds and border edges. In habit, Phlox subulata is non-invasive and cushion or mat-forming, the ‘cushions’ being made up of slender stems clothed with narrow evergreen leaves. Growth is moderately fast, and plants form a neat mound within several years. Masses of tiny saucer-shaped flowers are borne in late spring and early summer. Individually the blooms are small, from 1.5-3.5cm across, though produced in profusion so that the plant is smothered in colour. The only drawback is its relatively short flowering period, and while the foliage is evergreen and makes useful ground cover to prevent weed growth, it has no real ornamental value.

Phlox subulata blooms best in full sun and does grow reasonably well in partial shade, particularly in warmer areas where it benefits from a little shade during the hottest part of the day. Once established, Phlox subulata is mainly trouble free to grow although it may suffer from powdery mildew in periods of hot, dry weather, and also from stem and bulb eelworm. Phlox subulata is widely available in a range of colours.
