Most people know plants by their common names rather than by their botanical names, however, the botanical name is formal and internationally accepted. While we may commonly refer to a daisy, there are actually several species of daisies and the only way to know which species of daisy is being referenced, we need to know the botanical name. The botanical name has two parts, the first part identifying the genus to which the species belongs and the second part identifying the species within the genus. ‘Leucanthemum vulgare’ is the botanical name for a species of daisy and it explains that this species of daisy is a genus of flowering plants from the sunflower family. By using the botanical name we can avoid the confusion of multiple common names for the same plant.
