In the past wildflowers were very simply defined as plants that were not normally cultivated. That definition no longer applies because today the demand for wildflower plants and seeds is being met by producers. Wildflower species today are being further defined as:
• Native species–plants that occur naturally in a particular area without the intervention of human beings
• Indigenous species–plants that prosper in a distinct region or particular environmental habitat
• Naturalized species–plants that were first introduced by human beings and have now become established over time throughout an area
• Escaped varieties–plants originally introduced from other parts of the world, adapted to a particular region, and are now found in uncultivated portions of the region
