Description

Scarlet Flame Creeping Phlox (Phlox subulata) brings low-growing, high-impact color to rock gardens, borders, retaining walls, and slopes. This perennial groundcover forms a dense mat of evergreen foliage that erupts in brilliant red-pink blooms each spring—offering vibrant curb appeal and erosion control in one plant.

From seed, Scarlet Flame phlox is a reliable performer for those who value both beauty and practicality. Once established, it spreads steadily across poor or sandy soils, tolerates drought, and requires minimal care. The flowers attract early pollinators while the foliage stays neat year-round, making it an excellent filler for dry garden gaps or cascading over stonework.

We like Scarlet Flame for its ability to provide massive spring color with very little footprint. It’s easy to grow from seed, easy to maintain, and hard to forget once it’s in bloom.
