Moss phlox and creeping phlox are two terms that are often used interchangeably to refer to the same plant, Phlox subulata. However, there are some subtle differences between the two terms.
1. Common Names: Moss Phlox vs. Creeping Phlox
– Moss Phlox: Moss phlox is a common name that is often used to describe Phlox subulata. This name is derived from the plant’s low-growing and mat-forming habit, which gives it a moss-like appearance.
– Creeping Phlox: Creeping phlox is another common name for Phlox subulata. This name emphasizes the plant’s creeping growth habit, as it spreads along the ground.
2. Growth Habit:
– Moss Phlox: Moss phlox has a prostrate or creeping growth habit, with stems that spread out horizontally along the ground. It forms a dense mat of foliage, which can provide excellent ground cover in sunny areas.
– Creeping Phlox: Creeping phlox also has a low-growing and spreading habit, similar to moss phlox. It forms a thick carpet of foliage, which can help control soil erosion on slopes or fill in spaces between other plants in a garden.
3. Flowering:
– Moss Phlox: Moss phlox produces an abundance of small, star-shaped flowers in various colors, including shades of pink, purple, white, and blue. The flowers typically bloom in spring and create a stunning display when the plant is in full bloom.
– Creeping Phlox: Creeping phlox also produces similar small, colorful flowers that cover the plant in a carpet-like fashion. The flowers usually appear in early spring and continue to bloom for several weeks, attracting pollinators like bees and butterflies.
4. Cultural Requirements:
– Moss Phlox: Moss phlox is well-adapted to dry, rocky, and sunny locations, making it an excellent choice for xeriscapes or rock gardens. It prefers well-drained soil and can tolerate drought conditions once established.
– Creeping Phlox: Creeping phlox is also well-suited for sunny spots and can thrive in various soil types, including sandy or loamy soils. It is relatively low-maintenance and can tolerate dry conditions, making it suitable for rock gardens, slopes, or as a ground cover in sunny areas.
5. Varieties and Availability:
– Moss Phlox: Moss phlox is available in several cultivars, each with its unique flower color and habit. Some popular cultivars include ‘Emerald Blue,’ ‘Candy Stripe,’ and ‘Snowflake.’ These cultivars offer a range of flower colors and patterns to choose from.
– Creeping Phlox: Creeping phlox is also available in numerous cultivars, offering a wide array of flower colors, including pink, purple, red, and white. Some popular cultivars include ‘Scarlet Flame,’ ‘Drummond’s Pink,’ and ‘White Delight.’ These cultivars provide options for different color preferences and garden designs.
While moss phlox and creeping phlox are often used interchangeably, they refer to the same plant species, Phlox subulata. The terms highlight different aspects of the plant’s growth habit and appearance. Moss phlox emphasizes the moss-like appearance of the low-growing mat-forming plant, while creeping phlox emphasizes its spreading habit. Both varieties offer beautiful and colorful flowers, making them a great choice for sunny locations, such as xeriscapes, slopes, or rock gardens.
