The plant reaches a height of approximately 75-80 centimeters and forms sturdy flower stalks on which the decorative inflorescences appear in May. The hemispherical flower heads consist of countless star-shaped flowers that together form an airy and refined whole. The flowers are bright white, but what makes this cultivar truly special is the striking color contrast in the heart of the flower. The dark-colored ovary stands out beautifully against the light petals, giving the plant a striking graphic effect.

In addition, the broad pinkish-red stamens on the underside of the flowers create a subtle two-tone character. This gives the inflorescence extra depth and elegance. Although the description states that the flowers are fragrant, the cultivar is generally considered non-fragrant in gardening practice. Nevertheless, the flowers attract many bees and butterflies and make an important contribution to biodiversity in the garden.
