What does willowherb mean?
Willowherb is an English common name used for a group of herbaceous flowering plants, especially members of the genus Epilobium in the evening-primrose family. The best-known example is rosebay willowherb, a tall plant with narrow, willow-like leaves and spikes of purple-pink flowers. Other species carry related names, including great willowherb and broad-leaved willowherb, so the unqualified word does not identify one botanical species. Willowherb commonly occurs in disturbed ground, along railway lines, roadsides, and open areas where it can spread readily from its wind-dispersed seeds. In North America, rosebay willowherb is often called fireweed, although that name can also refer to unrelated plants. The word is mainly encountered in botanical, horticultural, and nature-writing contexts, where precise species names may be preferred. Its compound formation is especially memorable: the name describes the resemblance between the plant's leaves and those of a willow.
nounA common name for several herbaceous flowering plants in the evening-primrose family, particularly species in the genus Epilobium. The name is also used for rosebay willowherb and many related species with willow-like leaves.

"Purple rosebay willowherb spread across the newly disturbed ground beside the railway."
"The verge was crowded with purple rosebay willowherb."
"The guide identifies the plant as great willowherb rather than meadowweet."
The plural is uncommon in general use but may be used when referring to several distinct species of willowherb.
"Several willowherbs grow along the woodland edge."
Willowherb is named for a visual clue: its leaves were likened to those of the willow.

Where does willowherb come from?
Willowherb is an English compound formed from the words willow and herb, referring to a plant with leaves resembling those of a willow. Willow comes from Old English wilig, while herb comes from Old English herb, which was borrowed from Latin herba. Other English words such as herbage and herbaceous belong to the same Latin-derived family as herb.
How willowherb is actually used
Willowherb is chiefly a botanical common name rather than a general everyday word. Because several distinct species share names of this form, a more specific name is often needed to identify the plant.
