This plant was so-named because of the similarity of its leaves with those of Indian Hemp, Cannabis sativa (although Indian hemp leaves have five leaflets joined like a human hand, while Hemp Nettles comprise a single leaf). It should be noted quickly though that Hemp Nettles do not possess narcotic properties unlike the Indian Hemp! It is known as a pest plant to arable farmers, particularly potato farmers
