Why You’ll Love It

Centranthus ruber, commonly known as Red Valerian, is a tough and reliable perennial valued for its vibrant pink-red flower clusters that bloom generously from late spring through summer. The airy flowers sit above attractive blue-green foliage, creating a relaxed, naturalistic look that works beautifully in cottage gardens, gravel plantings, and mixed perennial borders. Extremely drought tolerant once established, Red Valerian thrives in poor, free-draining soils and brings colour, movement, and pollinator activity to sunny garden spaces with minimal care.

Planting & Care Tips

• Prefers well-drained soil; ideal for gravel and rocky sites

• Water sparingly once established

• Deadhead spent flowers to extend the blooming period

• Cut back after flowering or lightly in late winter to encourage fresh growth

• May self-seed in suitable conditions; remove spent flowers if control is required
