Papaver rhoeas (common names include corn poppy, corn rose, field poppy, Flanders poppy, red poppy, red weed, coquelicot, and, due to its odour, which is said to cause them, as headache and headwark) is a species of flowering plant in the poppy family, Papaveraceae. This poppy, a native of Europe, is notable as an agricultural weed (hence the "corn" and "field") and as a symbol of fallen soldiers.
The plant is a variable annual, forming a long-lived soil seed bank that can germinate when the soil is disturbed. In the northern hemisphere it generally flowers in late spring, but if the weather is warm enough other flowers frequently appear at the beginning of autumn.
Due to the extent of ground disturbance in warfare during World War I , corn poppies bloomed in between the trench lines and no man's land on the Western Front. Poppies are a prominent feature of "In Flanders Fields" by Canadian Lieutenant Colonel John McCrae, one of the most frequently quoted English-language poems composed during the First World War. During the 20th century, the wearing of a poppy at and before Remembrance Day each year became an established custom in most western countries. It is also used at some other dates in some countries, such as at appeals for Anzac Day in Australia and New Zealand.
In Menorca it is very commong at Spring.
