What type of flowers do violets primarily produce?

Violets primarily produce flowers that are often blue and yellow. The most commonly recognized species, such as the common blue violet (Viola sororia), typically feature purple or blue petals, often with a yellow center. This coloration is a characteristic aspect of violets, showcasing their appeal in gardens and natural landscapes. Additionally, the unique structure of violet flowers, which includes overlapping petals and a distinct spur, adds to their identification as part of the Viola genus, further emphasizing the relevance of blue and yellow in their flower traits.

In examining the other options, while some violets may have variations in color, the predominant association with blue and yellow is more accurately representative of the species. The presence of white and purple or other color combinations does not reflect the typical hues recognized in the most common violet varieties encountered in Pennsylvania and similar climates.
