Phyteuma
Phyteuma is native to Europe and Morocco. The species are herbaceous perennial plants, growing to 5 to 90 cm tall. The leaves are alternate, petiolate, and vary in shape on a single plant, with larger, broader leaves at the base of the stem and smaller, narrower leaves higher up; the leaf margin is serrated. The flowers are produced in dense erect panicles, each flower with a narrow, deeply five-lobed corolla, mostly purple, sometimes pale blue, white or pink. The fruit is a capsule containing numerous small seeds.
