lotus
An aquatic plant belonging to the Nelumbonaceae family of flowering plants. The lotus has prominent blooms (of pink or white hues) rising 8-12 inches above the water, each with a flattened central seed pod structure and fully circular leaves with centrally-attached stems. These features help distinguish it from the water lily flower (Nymphaea), with which it is often confused.
Nelumbo nucifera (also known as the Sacred or Indian Lotus) will probably be the plant of interest to Danbooru image taggers, being a divine symbol in Hinduism and Buddhism. It conveys the virtues of purity and non-attachment; it is associated with beauty, elegance, and grace.
