Abstract
Six evergreen ground-cover species including Ajuga reptans, Carex morrowii 'Variegata', Dianthus 'Night Star', Hedera helix 'Ivalace', Pachysandra terminalis, and Sedum rupestre, were tested for cold acclimation with three different light treatments (0, 30, and 70% of shading, respectively) to select potential candidates for over-wintering in central Korea. Among those species, Ajuga reptans, Carex morrowii 'Variegata', and Sedum rupestre performed well, which had more than 50% of survival rate in all light conditions. However, Dianthus 'Night Star' had less than 40% under any light treatment and the other two species, Hedera helix 'Ivalace' and Pachysandra terminalis, survived more than 40% only with 70% of shading condition. These results imply that those candidate species having less cold hardness in central Korea could have the potential to could over-winter as long as a proper light condition is provided.
