Phlox Grandiflora (Phlox drummondii var. grandiflora)

🌺 The large-flowered phlox — bigger blooms, taller stems

The grandiflora strain is bred for size: flower heads noticeably larger than standard phlox, carried on taller stems in a vivid mix of scarlet, rose, pink, lilac, salmon and white, many with a contrasting eye.

🌿 Quick Tips

1. Cover seeds with 3–4 mm of fine soil — phlox needs darkness to germinate.
2. Space 20–25 cm apart; the taller habit needs a little more room than dwarf types.
3. Pinch tips once at 10 cm for a bushier plant and more flower heads.
4. Deadhead regularly to keep it blooming for months.
5. Water at the base — wet foliage invites powdery mildew.
