The series unites compact deciduous shrubs with a height ranging from 60–90 cm to 120–150 cm. The plants have strong, upright shoots capable of supporting heavy inflorescences without lodging. The leaves are large, dark green, oval or ovate in shape.
The flowers are double or semi-double, gathered in corymbose or spherical inflorescences. The color of the inflorescences varies depending on soil acidity: from blue and purple shades on acidic soils to pink, crimson, or white on neutral and alkaline soils. Flowering lasts from June to September–October.
The plants are remontant and bloom repeatedly on the current year's shoots. The varieties in the series are considered reliable, but require winter covering to preserve flower buds, as frost resistance ratings vary from -18°C to -30°C depending on the source.
