Cupflowers are used in borders and rock gardens, as bedding and edging material, and in containers.

All summer long it gets covered in 1 inch, cup-shaped flowers that are blue-violet with yellow throats. Nierembergia scoparia is also mounded, but is shrubbier and taller, from 2-3 feet. Its leaves are also similar, but longer, to 2 inches. The 1 inch, cup-shaped, summer-appearing flowers are white with a blue tint
