The term “cupflower” typically refers to a type of flowering plant in the genus *Nierembergia*, which belongs to the nightshade family (Solanaceae). These plants are known for their cup-shaped flowers, which can be purple, white, or blue in color. They are often used in gardens and landscapes for their attractive blooms and ease of care. Additionally, the name “cupflower” can be used more broadly to describe any flower that has a cup-like shape.
