Variety description

10 August 2026

The variety is an interspecific hybrid combining traits of Coreopsis verticillata and Coreopsis grandiflora. The plant forms a dense bush 35–45 cm tall with narrow, finely dissected dark green foliage that retains its ornamental appearance throughout the season.

Flowers with a diameter of 6–8 cm have lemon-yellow petals with a fringed edge and a dark red center. The plant is resistant to lodging, powdery mildew, and adverse weather conditions. Flowering begins in the first year and continues until autumn, with deadheading stimulating the emergence of new buds.
