The study was conducted to investigate growth adaptability of Hosta species and introduced cultivars in outdoor gardens in Seoul, Korea. H. rectifolia 'Chionea', H. 'Blue Moon', and H. sievoldiana 'Frances Williams' showed brown leaves before July. In H. caerulea and H. 'Blue Angel', the browning symptom appeared during July to August. H. 'Fortunei Aureomarginata', H. 'Moerheimi', H. plantaginea, H. sieboldii 'Kabitan', H. 'Love Pat', H. 'Stilletto', and H. 'Zager's White Edger' showed no changes of leaf color at high temperature and light intensity. Changes of chlorophyll content in leaves were divided into two types. Non-changed types were H. 'halcyon', H. 'Hadspen Blue', H. August Moon', H. 'Invincible', H. lancifolia, H. 'Pearl Lake', H. 'Reyal Standard', H. 'Silver Crown', H. 'Zpunds', and H. plantaginea 'Aphrodite', whereas the others showed reduction in chlorophyll contents
