Phlox paniculata 'Mixed'
Phlox paniculata Mixed produces an uplifting blend of scented summer flowers in a range of shades, bringing a classic cottage-garden feel to borders and delivering plenty of stems for cutting.
These hardy perennials form upright clumps and typically reach around 1–1.5m tall, carrying dense heads of starry blooms that open over weeks, providing long-lasting colour through mid to late summer.
Plant in full sun or light partial shade in fertile, moisture-retentive, well-drained soil. Phlox appreciates consistent moisture and benefits from a mulched root run to help prevent stress in hot weather.
Water during dry spells and deadhead to encourage further blooms. Improve airflow by spacing plants well, and cut stems back to the base in late autumn after flowering has finished.
Ideal for mixed borders and wildlife-friendly gardens, phlox pairs beautifully with grasses and daisies, and the sweetly scented flowers are also loved by pollinators throughout the summer.
