內容簡介top Weeds 簡介 At first thought weeds seem to be nothing more than intruders in a well-manicured lawn. But in reality a weed is only a weed because it has been deemed so; they spring up where they are not wanted, so they are removed without a second thought. But the idea of a weed is constantly changing, with the definition shifting based on the context. In a field of corn the scarlet poppy is considered to be a weed, because it does not belong with the rest of the crops. But in history what we now consider to be weeds once had practical uses; from Neolithic times until the early sixteenth century, the weed called at hen?was considered a vegetable, and its seeds were used to make flour. Yet despite the idea that weeds can be helpful to our ecology, they are still considered to be harmful, a nuisance in our gardens. Weeds by Nina Edwards discusses the history of weeds, and how certain plants come to be regarded as weeds and not others. Sprinkled with personal anecdotes and full of useful information,Weeds is a helpful resource for understanding exactly what turns an ordinary plant into a weed in varying contexts.
