Red Valerian Flower Seeds

Centranthus ruber, commonly known as Red Valerian, is a hardy cottage garden perennial loved for its clusters of vibrant red flowers that bloom for months through the warmer seasons well into autumn. Its airy flower heads and relaxed growth habit bring colour, height, and movement to garden beds, borders, pathways, and naturalistic plantings. Red Valerian thrives in full sun and well-drained soil, performing especially well in poor or dry soils once established. This low-maintenance perennial is drought-tolerant, easy to grow, and ideal for filling tricky spots such as retaining walls, gravel gardens, and sunny slopes. A favourite with bees, butterflies, and other pollinators, it is perfect for cottage gardens, cut-flowers, and meadow-inspired spaces where long flowering colour and effortless charm are desired.
