A new hybrid variety of pasqueflower, 'Yeonhong', was derived from an interspecific cross between Pulsatilla davurica and P. koreana at the Jeollanamdo Agricultural Research and Extension Services (JARES) in Naju, Korea. The original cross was performed in 2001, and the 'Yeonhong' hybrid was established in 2003 after two years of selective breeding. 'Yeonhong' is characterized by deep pink flowers and is self-incompatible. The inherent characteristics of the variety are deep yellow anthers, a deep pink stigma, six petals, and green leaf color. 'Yeonhong' blooms twice a year. The agronomic characteristics of the variety are 26.5 flowers per plant, 58.6 cm in flower height, 46.8 cm in cut flower length, 11.5 cm in bract width, and 34.4 cm in leaf length. Flower characteristics include 8.4 days of longevity for cut flowers and 34 days of longevity for bracts. The new variety is suitable for use as a cut flower.

Karyotypes were established in five Pulsatilla species from Korea : P. cernua, P. davurica, P. koreana, P. chinensis and P. tongkangensis. The somatic chromosome numbers of five species were all 2n=2x=16 with the basic number of x=8. The chromosome complement of P. cernua consisted of 5 pairs of metacentric, 1 pair of submetacentric and 2 pairs of subtelocentric. P. davurica, P. koreana and P. chinensis consisted of 5 pairs of metacentric and 3 pairs of subtelocentric. P. tongkangensis consisted of 5 pairs of metacentric, 2 pairs of submetacentric, and 1 pair of subtelocentric. Karyotype formulas of P. davurica, P. koreana, and P. chinensis were the same as K (2n) = 2x = 16 = 10m + 6st, while those of P. cernua was K (2n) = 2x = 16 = 10m + 2sm + 4st and P. tongkangensis was K (2n) = 2x = 16 = 10m + 4sm + 2st, respectively.
