The RHS have awarded Phlox douglasii 'Red Admiral' an AGM (Award of Garden Merit), and it's easy to see why. The hardy perennial's green foliage forms a dense mat which suppresses weeds. It is a disease resistant, versatile plant that grows vigorously while remaining compact. In the early spring, Moss Phlox bursts into bloom, producing bright pink flowers that are sure to transform borders, patio containers and rockeries alike into colourful displays. Height: 15cm (6); Spread: 30cm (1'0).
