We report a technique for obtaining seeds of ‘Cheongnarae’ (a variety of Hosta minor cultivated at the Korea National Arboretum in 2019) by artificial crossing of H. minor , collected from Jeju Island, as the female parent and H. minor ‘Krossa Regal’, cultivated outside Korea, as the male parent. Among the individuals obtained after sowing, those that showed different morphological characteristics, such as leaf shape and color, were selected. Among these individuals, those with thick leaves and light-colored flowers were further selected. Vegetative propagation and cultivation steps were repeated for evaluation of the characteristics. ‘Cheongnarae’ has relatively thicker leaves and a darker color (RHS 137A) than the control variety ‘Black Hills’ and has wings at the point where the petiole meets the leaf blade. The shape of the leaf blade edge is clearly sinuous, and the flower color is close to white (White N155B). ‘Cheongnarae’ cultivated in this way can be used for pot plant or gardening.
