Compact shrub with a height and width of 60–90 cm. Inflorescences are of the lacecap type with a flat center of fertile florets surrounded by a ring of large double sterile florets resembling water lilies. Leaves are dark green with serrated edges and may take on bronze-red hues in autumn.
The variety is remontant, blooming on both old and new wood from early summer until frost. Flower color depends on soil acidity: they acquire a blue hue in acidic environments and pink in neutral or alkaline ones. USDA hardiness zones: 5–9.
The plant has sturdy stems and is used in landscape design and container cultivation. It is relatively undemanding, though it may be susceptible to powdery mildew under conditions of poor air circulation.
