Centranthus Ruber (Red Valerian) is a hardy flowering perennial admired for its upright stems, blue-green foliage and abundant clusters of small star-shaped flowers in rich red to pink shades. Its relaxed, naturalistic form brings colour and texture to borders, cottage gardens, rockeries and informal landscapes.
Centranthus Ruber (Red Valerian) is well suited to sunny, well-drained positions and is particularly useful for dry or low-maintenance gardens once established. The long flowering season provides valuable colour through the warmer months, while the nectar-rich flowers attract butterflies, bees and other beneficial pollinators.
