A new cultivar of Gaura lindheimeri, \u2018HARROSY\u2019, characterized by its flowers that emerge from crimson red buds and have flower petals that are white in color with pink margins. According to a preferred embodiment, the water intake includes dual channels to allow the uptake of dedicated streams of water. The arrangement of the pixels is designed taking account of the intensity profile of an image of a nominal human pupil in the nominal window plane formed in the pixel plane by the spatially multiplexing parallax element to reduce the amount of spatially derived flicker observed by a viewer moving in the window plane. The inner side cylindrical portion and an upper radial dynamic pressure groove array are superimposed in a radial direction.
