Himalayas, and is sometimes included in
D. cannabina. It grows to about 2.0 m tall, and in May to August it produces small greenish-yellow flowers. This species is strictly
dioecious, with male and female flowers on different plants. It is grown for ornamental foliage and can be used to produce a
laxative and a yellow dye. The North American species
