Red valerian (Centranthus ruber)

Red valerian (Centranthus ruber) is a hardy perennial that thrives in alkaline soils and can often be seen growing in rocky crevices or even on old stone walls. It prefers sunny locations and can tolerate drought conditions. Unlike true valerian, red valerian is not known for any medicinal properties, although its leaves and roots can occasionally be used in culinary applications, such as salads or soups.
