Phlox 'Blue Boy' or Tall Garden Phlox is a highly coveted cottage garden classic celebrated for its striking, color changing flowers and sweet, nostalgic fragrance. It forms an upright, structural clump of clean green, lance shaped leaves topped with large, dense pyramidal clusters of heavily scented, five petalled blossoms. In direct summer sun, the flowers showcase a beautiful, rich lavender-blue tone with a small white central eye, which magically shifts into a deeper, cool blue-violet hue in the shade or during twilight hours. It is an indispensable vertical accent choice for sunny mixed borders, cutting gardens, and sensory-focused landscapes.
