Landscape with Wildflowers. A wildflower is a flower that grows in the wild, meaning it was not intentionally seeded or planted. The term implies that the plant is neither a hybrid nor a selected cultivar that is any different from the native plant, even if it is growing where it would not naturally be found. The term can refer to the whole plant, even when not in bloom, and not just the flower. Wildflower is an imprecise term. More exact terms include: native species naturally occurring in the area. exotic or introduced species not native to the area, including invasive species that out-compete other plants, whether native or not. imported. naturalized are imported but come to be considered by the public as native. In the United Kingdom, the organization Plantlife International instituted the County Flowers scheme in 2002, see County flowers of the United Kingdom for which members of the public nominated and voted for a wildflower emblem for their county. The aim was to spread awareness of the heritage of native species and about the need for conservation, as some of these species are endangered.
