A wildflower is a flower not intentionally seeded or planted. Yet "wildflower" meadows of a few mixed species are sold in seed packets. The term "wildflower" has been made vague by commercial seedsmen who are interested in selling more flowers or seeds more expensively than when labeled with only its name and/or origin. The term implies that the plant probably is neither a hybrid nor a selected cultivar that is in any way different from the way it appears in the wild as a native plant , even if it is growing where it would not naturally.

Scientists do not refer to wildflowers and generally try to discourage people from using the term altogether. Terms like native species (naturally occurring in the area, see Flora (plants)), exotic or, better, introduced species (not naturally occurring in the area), of which some are labelled invasive species (that out-compete other plants – whether native or not), imported (introduced to an area whether deliberately or accidentally) and naturalized (introduced to an area, but now considered by the public as native) are much more accurate.
