Weed

Unwanted wild plants, particularly those springing up in a cultivated area, are known as weeds. Generally, weeds are hardy flowering plants which reproduce easily. with small, insignificant flowers. Many weeds can be wind-pollinated. However, even useful plants can become naturalised in an area and become weeds. When weeds grown so quickly that they take over the environment of other species, or make it difficult or impossible to farm an area, they are known as noxious pests. Sometimes, even cultivated plants can become so invasive that they are considered weeds. This can happens when plants are moved to an area they are not native to, particularly areas with warm, hospitable climates and fertile soil.
