Phlox paniculata 'David'
Phlox paniculata ‘David’ produces large heads of pure white, sweetly scented flowers that light up summer borders and bring a fresh, classic look to cottage and wildlife-friendly planting.
Forming an upright clump to around 1–1.5m tall, it flowers over many weeks in mid to late summer, with dense, starry blooms that open progressively and provide plenty of long stems for cutting.
Plant in full sun or light partial shade in fertile, moisture-retentive, well-drained soil. Phlox performs best with consistent moisture and benefits from an annual mulch to keep roots cool.
Water during dry spells and deadhead regularly to prolong flowering, then cut stems back to the base in late autumn. Division in spring or autumn can refresh older clumps and improve vigour.
Ideal for borders and cutting gardens, ‘David’ pairs beautifully with grasses and daisies, and the nectar-rich flowers are highly attractive to bees and butterflies throughout the summer.
