Weeds and invasive plants are part of life for everybody involved with managing vegetation in any form. This has been true since humans first promoted the growth of a useful plant species over another of lesser value. As we modify our environment to suit our needs, such changes also suit the needs of some plants which proliferate in the habitats we create. Some of weed species have a long history in association with humans while others are building new relationships. The negative impacts that plants can have on our lives depends on many aspects of the plants and ourselves. How we view the landscape around us and what prejudices we harbour can be just as important in defining a weed as any real harm that plant may cause. It is important to realize that many plants long cherished by gardeners have caused and are causing real harm to others and rightfully bear the title of noxious weed.
