Centranthus angustifolius is a herbaceous perennial plant belonging to the family Caprifoliaceae. It is commonly known as narrow-leaved valerian or spur valerian due to its narrow, lance-shaped leaves and spur-like flower shape. The plant is native to the Mediterranean region and can be found growing on rocky slopes, cliffs, and in open woodlands. It typically grows to a height of 60-90 cm and produces clusters of pink, white, or purple flowers from June to September. Centranthus angustifolius is a valuable plant in ornamental gardening and landscaping due to its attractive flowers, ability to attract pollinators, and tolerance of drought and poor soils. It has also been used in traditional medicine for its anti-inflammatory and sedative properties.
