Phlox paniculata 'Purple Eye' – Planting & Care Guide

About Phlox paniculata 'Purple Eye'

Phlox paniculata 'Purple Eye', commonly known as Garden Phlox, is a beautiful herbaceous perennial producing large, rounded clusters of pure white flowers, each with a distinctive deep purple eye at the centre. Flowering from mid-summer into early autumn, it provides weeks of vibrant colour and a light, sweet fragrance that attracts bees, butterflies and other pollinating insects.

Growing to approximately 60–80cm tall with a spread of 45–60cm, 'Purple Eye' forms upright, bushy clumps with lush green foliage, making it an excellent choice for mixed borders, cottage gardens and cutting gardens.

Planting Guide

• Plant in full sun or light partial shade.
• Full sun encourages the best flowering.
• Prefers fertile, moisture-retentive but well-drained soil.
• Suitable for loam, clay and sandy soils enriched with organic matter.
• Improve the soil with compost or well-rotted manure before planting.
• Dig a planting hole twice the width of the root ball and the same depth.
• Position the crown level with the surrounding soil.
• Backfill, firm gently and water thoroughly.
• Apply a mulch around the base to retain moisture and suppress weeds.
• Space plants approximately 45–60cm apart to allow good air circulation.

Care & Maintenance
