What feature does the American lotus plant's flowers have that distinguishes it?

The American lotus plant is distinguished by its showy flowers, which can reach up to 6 inches in width. This characteristic contributes to their prominence in aquatic ecosystems as well as their aesthetic appeal in landscapes. The large size and vibrant nature of the flowers make them visually striking, which is a crucial aspect when identifying the species. Showy flowers often attract pollinators and play a significant role in the reproductive cycle of the plant.

In contrast, the other characteristics mentioned do not accurately describe the American lotus. For instance, the plant does not have a uniform flower color, as they can be white or variations in color, though yellow is a common misconception. Additionally, the flowers are significantly larger than 2 inches, which rules out any confusion with smaller flowers from other species. Purple flowers are not characteristic of the American lotus, further solidifying the distinct nature of its blooms.
