Arctium tomentosum, commonly known as the woolly burdock [2] or downy burdock, is a species of burdock belonging to the family Asteraceae. [3]
Arctium tomentosum is a biennial herbaceous plant. The stem is erect, with ascending branches. It can reach a height of about 2 metres (6 ft 7 in). Leaves are grayish white and quite felted, green and glabrous toward the stem. Basal leaves are petiolate. Leaf blade is heart-shaped, with rather denticulater margins. They can reach a length of 20–50 centimetres (7.9–19.7 in) and a width of 10–30 centimetres (3.9–11.8 in). Flowers are purplish red, with a diameter of 0.9–1.2 centimetres (0.35–0.47 in). This species can be distinguished from related ones because the underside of the leaves is covered with white woolly hairs.[ citation needed ] Flowers and fruits appear from July to September. [4] [5]
Arctium tomentosum was first described by the English botanist Philip Miller in 1768. [6]
Arctium tomentosum is native to Eurasia from Spain [7] to Xinjiang Province in western China. [5] It is also naturalized in other parts of the world such as North America. [8]
