The bush has a broad, upright shape and large dark green foliage. Flowering is abundant and prolonged, lasting from spring to early autumn. The flowers are colored in yellow-green and pink tones.
The inflorescences at the beginning of development resemble a lacecap with fertile flowers in the center and decorative ones along the edges. As they develop, the decorative flowers fill the entire inflorescence, giving it a dense and double appearance. The plant has a deep root system and strong flower stalks resistant to lodging.
The variety is intended for decorative use in gardens and container cultivation. Frost resistance can reach -22°C depending on climatic conditions and the presence of cover.
