Centranthus ruber Fr: Centranthe rouge
This is a common and conspicuous plant, with its clusters of flowers growing along the roadsides throughout the region. In spite of the name, the thousands of flowers we've seen growing so far have all been pink, rather than red. The stems are tall and bluish-green, with a waxy surface.
