Phlox subulata ‘Emerald Cushion Blue’ (Creeping Phlox)
Alpine Phlox 'Emerald Cushion Blue', Moss Phlox 'Emerald Cushion Blue', Creeping Phlox 'Emerald Cushion Blue'
Phlox subulata ‘Emerald Cushion Blue’ (Creeping Phlox) is a popular evergreen perennial with masses of pale lavender-blue flowers which enthusiastically blanket the dark green glossy foliage in mid to late spring. Vigorous, it forms a lovely cushion and adds splashes of color for about 3-4 weeks. Excellent disease resistance. Perfect for rocky areas, slopes and flower borders.
- Mat-forming, Phlox subulata grows only 4-6 in. tall (10-15 cm) but spreads vigorously up to 2 feet wide (60 cm) in a beautiful flower carpet resembling moss, hence the common name of moss phlox.
- Prefers full sun (tolerates dappled shade) and enjoys humusy, medium moisture, well-drained soils. It thrives in sandy or gravelly soils and is drought tolerant once established. Good drainage required!
- Excellent choice for rock gardens, slopes, edgings or ground covers. Perfectly suited to border fronts and lovely when slightly draping a rock wall. A great companion for tulips and daffodils… and butterflies too!
- Hardy, Phlox subulata is trouble-free, deer resistant, salt tolerant and requires little care.
- Shear after flowering to maintain a neat form and promote new foliage, with the resultant increase in blooms next spring. This plant will multiply in optimum growing conditions.
