Honey plants are considered a major role in the production of honey and pollen in the beekeeping industry. In South Korea, most production of honey has largely relied on a limited flowering plant, black locust (Robinia pseudoacacia). However, the forests of R. pseudoacacia have been gradually declined in South Korea because the Leaf-yellowing of black locust has widely spread to most regions since early 21st Century. Therefore, alternative honey plants should be studied to resolve the severe reliance on black locust in Korean beekeeping. Although 610 species of honey plants are known from South Korea, the foraging activity of honey bees (Apis cerana andA. mellifera) and seasonal compositions of each region were poorly studied on them. In this study, we investigated 37 species of honey plants for estimating the foraging activity of honey bees for them and 41 species of honey plants for evaluating their seasonal composition in the central area of South Korea. As a result, the following 16 trees and herbs were found as honey plants showing a high level of honeybees activity.Buxus microphylla var.koreana,Prunus yedoensis, Rubus crataegifolius, Rhododendron schlippenbachii, Staphylea bumaldai, Robinia pseudoacacia, Rosa multiflora, Cirsium japonicum var. ussuriense, Trifolium repens, Ilex verticillata, Zizyphus jujuba var. inermis, Tilia amurensis, Koelreuteria paniculata, Fagopyrum esculentum, Perilla frutescens var. japonica, and Dendranthema zawadskii var. latilobum. On the seasonal composition of honey plants, Pyrus ussuriensis, Tilia amurensis, T. mandshurica, Impatiens textori, Dendranthema boreale, Elsholtzia ciliata, and Agastache rugosa were considered major honey plants in Inje county, as well as Prunus spp., Robinia pseudoacacia, and Castanea crenata.
