Herbs of the Genus Heracleum

Species of the genus Heracleum are found throughout the world. They are native to Asia, Africa, and the temperate northern hemisphere. They are often called hogweed, and are used as garden plants. They are herbaceous, meaning that they grow in clusters, and produce large flower clusters.

Some species of hogweed are poisonous to humans, and can cause severe burns. Others are used as a source of dye, and are eaten by many people in North America. They are also consumed by cattle and livestock. They are also known to attract beneficial insects, such as the Anise Swallowtail butterfly. The dried stems are often used to make flutes for children. The dried roots can also be used to treat pain and other ailments. However, they should be disposed of carefully, because the sap they contain can cause serious burns within 24 to 48 hours.

Unlike other Heracleum species, the genus Heracleum giganteum was not introduced to the United States, but it was imported to Europe. It was initially imported as an ornamental plant, but it quickly became an invasive species. It was planted in ornamental gardens and arboreta in Britain, and continued to spread until the 20th century. In the nineteenth century, it was also used by beekeepers. Eventually, it was planted in Victorian gardens in Canada.

The first recorded naturalized population of the genus Heracleum was in Cambridgeshire, England, in 1828. The genus Heracleum is known to have a number of garden ornamentals, and several fodder crops. It has a conspicuous appearance, and its leaves are large and rough. The flowers are fragrant and are arranged in umbels. They bloom in the summer.

The genus Heracleum has many varieties, including two species that are found in North America. The species Heracleum maximum is the most common. It grows up to three to ten feet in height, and has large, rough, hairy leaves. The flower is an umbrella-shaped cluster with five petals. It blooms mid-summer. The leaves are divided into three segments and are about 18 inches wide. The seeds contain inhibitors, and can delay the germination of other seeds. They are eaten by many people, and are used to make yellow dye.

The genus Heracleum contains several garden ornamentals and fodder crops, including H. sphondylium, a species that is commonly used in the UK. This plant is smaller than the giant hogweed, and is often confused with it. The seeds are especially inhibitory, and delay the germination of Salix. They can also cause rashes and irritation. They also inhibit root elongation.

Heracleum is a genus of perennial herbs, which are widely distributed in the world. They are found in high mountains as far south as Ethiopia, and in the temperate northern hemisphere. There are 148 species accepted by Plants of the World Online, but most of them are not listed as medicinal plants. They are used as plant borders, and their young stalks are eaten raw by many people in North America.
