Galega officinalis L. |
Galega officinalis, commonly known as galega,goat's-rue,French lilac,Italian fitch, or professor-weed, is an herbaceous plant in the Faboideae subfamily. It is native to the Middle East, but it has been naturalized in Europe, western Asia, and western Pakistan. The plant has been extensively cultivated as a forage crop, an ornamental, a bee plant and as green manure.
The name is believed to derive from the Greek terms for milk (gala) and goat (aigos), because medieval Europeans noticed that it increased milk production in livestock when eaten. However, the plant has proved too toxic for widespread agricultural use, with the potential to induce a buildup of excess fluid in the lungs, pleural cavities, or trachea, low blood pressure, paralysis and death., hence the name "Goat's rue". Galega bicolor is a synonym. It is a hardy perennial that blooms in the summer months.
G. officinalis is used as a food plant by the larva of Coleophora vicinella, a species of moth.
In 1891, G. officinalis was introduced to Cache County, Utah, for use as a forage crop. It escaped cultivation and is now a weed and agricultural pest, though it is still confined to that county. As a result, it has been placed on the Federal Noxious Weed List in the United States. It was collected in Colorado, Connecticut and New York prior to the 1930s, and in Maine and Pennsylvania in the 1960s, but no more collections have been made in these areas since and the populations are presumed to have died out. It has also been found in Argentina, Chile, Ecuador, and New Zealand.
