Fun Facts
- 🌱 The common name 'Moss Phlox' refers to the moss-like, fine foliage rather than any relation to actual moss; it earned this name due to its low, cushion-forming growth habit.
- 🌱 Phlox flowers are highly fragrant, especially in the evening and on warm days, releasing a sweet scent that attracts night-flying moths and early pollinators.
- 🌱 This cultivar is exceptionally tough and can survive in poor, rocky soils where many other plants fail, making it a favorite for xeriscaping and low-maintenance gardens.
